In this project, you are asked to use data from a Survey that Sr. Barbara conducted in her MT 120 classes to determine whether the students in the class were randomly guessing the identities of the two men in the photos. This part of the project will be a lot like several of the explorations of Chapter 1, where you are using a statistic (, and using an applet to calculate a p-value. Does the p-value support the idea that the students were guessing, or does the p-value suggest that students were doing something other than guessing?
If the students were doing something other than guessing, use the statistic ( from the data to estimate a reasonable value for the parameter (π). This part of investigation goes beyond what have been learned already in this class, and challenges to experiment a bit to find a better estimate for the true population parameter for this scenario.
Background: A study in Psychonomic Bulletin and Review (Lea, Thomas, Lamkin, and Bell, 2007) presented evidence that "people use facial prototypes when they encounter different names." Participants in that study were given photos of two faces and asked to identify which face is "Tim" and which is "Bob." Sr. Barbara is replicating this study with students in her MT 120 Applied Statistics classes. On September 26 - 27, she asked students in all three sections of MT 120 to identify from two photos, which face belongs to "Bob" and which to "Tim." Were her students simply guessing, or were they doing something other than guessing?
On September 26 and 27, Sr. Barbara gave her students an opportunity to participate in a quick survey about Tim and Bob. She asked the students to quickly identify whether the face on the left belongs to a man named Tim or to a man named Bob. Forty-two students completed this survey. The results of this survey is that 9 students said that Bob was on the left while 33 students said Tim was on the left.
1. Data Collection Methods:
To replicate the study that appeared in Psychonomic Bulletin and Review, Sister Barbara did not ask "all people" to identify the men in the photos, but rather just a sample from a larger population. You may recall that she asked you to look at photos of two men, and to identify whether the face on the left was Bob or Tim.
· How, where, and when was this data collected? Who did Sister Barbara survey?
· Who or what are the observational units, and what is the variable for each observational unit? What is the statistic?
· What does this sample (students in Sr. Barbara's MT 120 classes) suggest to us about the larger population? Did Sister Barbara take a simple random sample to collect this data? Do you think it is reasonable for her to assume that this sample is representative of some larger population?
· What is the population to which it would be reasonable to extend these results? Does it seem reasonable to extend the results of this study to all undergraduate students at Cardinal Stritch University? To the population of all students (both grads and undergrads) at Stritch? To people beyond Stritch? All people in the United States? Beyond the United States? Why?
2. Summary and Conclusions:
White a paragraph summarizing this study.
· What did you learn about students in Sr. Barbara's classes, Stritch students, or people in general? Do these results surprise you? Why?
· If the p-value suggests that Sr. Barbara's students were doing something other than simply guessing, suggest a better value for the parameter (or an interval of plausible values for the parameter). Explain how you determined a plausible value (or interval of plausible values) for the parameter. This question asks you to go beyond what you've learned (so far) in this course. Use critical thinking to identify a reasonable value (or interval of possible values) for the parameter. Explain how your are doing this.
· What do you think is going on here? Do you think the students were guessing, or is something else going on?

Find the value of x.
Answer:
64 = x
Step-by-step explanation:
The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel
128 = 2x
Divide each side by 2
128/2 = 2x/2
64 = x
Answer:
x = 64
Step-by-step explanation:
We know that,
If lines are parallel, the alternate angles are also equal.
Therefore,
[tex] \sf2x = 128[/tex]
Now, let us solve for x.
For that, divide both sides by 2.

Use point-slope form to write the equation of a line that passes through the point (8,17) with slope 3/2 .
The equation of the line with the given properties is y - 17 = 3/2(x - 18)
What are linear equations?Linear equations are equations that have constant average rates of change.
How to determine the equation of the line in point-slope form?The points are given as
(8, 17)
The slope is given as
Slope = 3/2
Calculate the slope of the points using
m = (y2 - y1)/(x2 - x1)
Where
Slope = m = 3/2
(x1, y1) = (8, 17)
So, we have
3/2 = (y - 17)/(x - 8)
Cross multiply in the above equation
So, we have
y - 17 = 3/2(x - 18)
A linear equation is represented as
y = m(x - x1) + y1
In point-slope form, we have
y - y1 = m(x - x1)
By comparing y - y1 = m(x - x1) and y - 17 = 3/2(x - 18), we can see that
y - 17 = 3/2(x - 18) is in point-slope form
Hence, the equation in point-slope form of the line that passes through the point (8, 17) is y - 17 = 3/2(x - 18)

Answer:
Either of ...
reflection across the y-axis, and translation down 6reflection across the x-axis and translation down 4Step-by-step explanation:
You want the transformations that take f(x) = 3x+1 to g(x) = -3x-5.
TransformationThe x-term of the transformed function has a sign opposite that of the original function. That can be accomplished by either of (a) reflection across the y-axis (replaces x by -x), or by (b) reflection across the x-axis (replaces f(x) by -f(x)).
Either way, an additional translation is required. That translation can be either vertical or horizontal, and may be done either before or after the reflection.
Horizontal reflectionReflecting f(x) across the y-axis means it becomes ...
f(-x) = 3(-x) +1 = -3x +1
In order to make that into -3x-5, we must add -6 to the function value:
g(x) = f(-x) -6 = (3(-x)+1) -6 = -3x -5
F(x) will be taken to g(x) = -3x-5 by reflection across the y-axis and translation down 6 units.
Vertical reflectionReflecting f(x) across the x-axis means it becomes ...
-f(x) = -(3x +1) = -3x -1
In order to make that into -3x-5, we must add -4 to the function value:
g(x) = -f(x) -4 = -(3x +1) -4 = -3x -5
F(x) will be taken to g(x) = -3x-5 by reflection across the x-axis and translation down 4 units.
__
Additional comment
As noted above, the translation can be either horizontal or vertical. For example, translating the function 2 units to the right makes it f(x-2). Then reflection across the y-axis replaces x by -x, so we have ...
g(x) = f(-x-2) = 3(-x-2)+1 = -3x -6 +1 = -3x -5
To get g(x), we could translate right 2 units, then reflect across the y-axis.
We also note that point (-1, -2) is shared by f(x) and g(x), so reflection horizontally across the line x=-1, or vertically across the line y=-2 would also give the required transformation.

If 13800 adult Pacific newts made their annual migration between November 2020 and March 2021, Roughly 2/5 didn't survive the trip, then the number of newts survived crossing the road is 8280 newts
The number of adult Pacific newts made their annual migration = 13800
Roughly 2/5 didn't survive the trip
Then the number of newts didn't survive = 13800×(2/5)
= 13800×0.4
= 5520 newts
To find the number of newts survived, we have to use subtraction
The number of newts survived crossing the road = 13800-5520
= 8280 newts
Hence, If 13800 adult Pacific newts made their annual migration between November 2020 and March 2021, Roughly 2/5 didn't survive the trip, then the number of newts survived crossing the road is 8280 newts

Decide whether the random variable x is discrete or continuous. Explain your reasoning. Let x represent the time it takes to run a mile. Is the random variable x discrete or continuous?
The variable represents time. The time in which a person runs a mile will depend on the speed of that person, and that can take almost any value, thus, here the variable is continuous.
Is the variable discrete or continuous?First, when a variable is discrete and when it is continuous?
A variable is discrete if it only can take some selected values on a given interval, while a variable is continuous if it can take any value (or at least a dense set) of values in that interval.
For example, the numbers that one can roll on a dice form a discrete set, because the values can only be {1, 2, 3, 4, 5, 6}, just to given an example.
Now, in this case, the variable represents time. Time almost always is a continuous variable, in this case, the time is the time in which a person runs a mile. So that variable can take almost any value (depends on the speed of the person).
So we conclude that this is a continuous variable.

From the table function 2 it can be observed that the value of y is one third of x. The mathematical expression of function 2 is,
[tex]y=\frac{1}{3}x[/tex]So rate of function 2 is also 1/3.
Thus function 1 and function 2 have the same rate, 1/3.
what's the result of adding these two polynomials: (2x+y+1) + (2x⁶-y+1)? I'm doing a test and the correct answer says is 4x⁶-2y+1 but I'm not very sure it is the correct one. Can someone help me? :3
Answer
[tex]\begin{equation*} 2x^6+2x+2 \end{equation*}[/tex]Step-by-step explanation
Given the polynomials:
[tex]\begin{gathered} 2x+y+1 \\ \text{ and} \\ 2x^6-y+1 \end{gathered}[/tex]To add them we need to add the similar terms (terms with the same variable and degree), as follows:
[tex]\begin{gathered} (2x+y+1)+(2x^6-y+1)= \\ =2x^6+2x+(y-y)+(1+1)= \\ =2x^6+2x+2 \end{gathered}[/tex]
