Answers
Answer:
133

(Need help ASAP, I’m taking a test) A researcher is 95% confident that the interval from 5.09 to 10.13 captures x = the true mean amount of
times models change clothes during a fashion shoot.
Is it plausible that the true mean number of times for all models to change clothes during a fashion shoot may
be 102
No, this is not a plausible value for the population mean, because 10 is within the 95% confidence interval
No, this is not a plausible value for the population mean, because 10 is not within the 9596 confidence
interval
Yes, this is a plausible value for the population mean, because 10 is within the 95% confidence interval
Yes, this is a plausible value for the population mean, because 10 is only a little bit above the upper
boundary of the 95% confidence interval.
Answers
Answer:
See below
Step-by-step explanation:
If a proposed value is outside the confidence interval, it is not a plausible value because the interval never catches it. So B is your best choice.

P(m1) 26/46 for pick on.. but that removed one male from the population and also one from the total
P(m2) 25/45
now multiply those two fractions together to get the total probability
26/46 * 25/45 = 650/2070 obviously reduce fraction

Answers
Answer:
990 cars
Step-by-step explanation:
Find how many cars pass through at 6am, t=0:
r(0)= 300+600(0)-90(0²) = 300
Find how many cars pass through at 9am, t=3:
r(3)= 300+600(3)-900(3²)=300+1800-810=1290
Find the difference (how many cars pass between 6am and 9am): 1290-300=990

Remember that the equation to graph a linear graph or line is y=mx+b
m is your slope and b is your y intercept. Since your line hits the y-axis at y=1, b=1.
solve y=f(x) for x then find the input when the output is 6
f(x)=x+9
Answers
x = -3
So to figure this out we can readjust the equation to make it easier to solve
[tex]f(x) = x + 9[/tex] is equal to [tex]x+9 = 6[/tex]
From here we can just subtract 9 from both sides and we get our answer!
[tex]x+(9-9) = (6-9)\\x = -3[/tex]

Computer Action Company sells computers and computer parts by mail. The company assures its customers that products are mailed as soon as possible after an order is placed with the company. The distribution of the times taken to mail products is known to follow a normal distribution. A sample of 28 recent orders showed that mean time taken to mail products for these orders was 70 hours and the standard deviation was 14 hours. If you were asked to find a 95% confidence interval for the mean time taken to mail products for all orders received at the office of this company, would you use z or t
Answers
Answer:
The t distribution is used, because we have the standard deviation for the sample.
Step-by-step explanation:
When to use the z or the t distribution?
When we have the standard deviation for the population, we use the z distribution.
When we have the standard deviation for the sample, we use the t distribution.
In this question:
We have the standard deviation for the sample, which means that the t distribution is used.
how many ways can three people be selected from a group of seven people if order does matter

In how many ways can be selection be done
Since orders does matter, then it is permutation.
This is calculated as:

So, we have:
[tex]^7P_3 = \frac{7!}{(7-3)!}[/tex]

Suppose that the TSH (Thyroid Stimulating Hormone) levels among healthy individuals are normally distributed with a mean of 3.3 unitsmL. Suppose also that exactly 98% of healthy individuals have TSH levels below 5.9 unitsmL. Find the standard deviation of the distribution of TSH levels of healthy individuals. Carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal plac
Answers
Answer:
The standard deviation of the distribution of TSH levels of healthy individuals is of 1.2658 units/mL.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 3.3 units/mL
This means that [tex]\mu = 3.3[/tex]
Suppose also that exactly 98% of healthy individuals have TSH levels below 5.9 units/mL.
This means that when [tex]X = 5.9[/tex], Z has a pvalue of 0.98. So Z when X = 5.9, has a pvalue if 0.98, that is, Z = 2.054. We use this to find [tex]\sigma[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.054 = \frac{5.9 - 3.3}{\sigma}[/tex]
[tex]2.054\sigma = 2.6[/tex]
[tex]\sigma = \frac{2.6}{2.054}[/tex]
[tex]\sigma = 1.2658[/tex]
The standard deviation of the distribution of TSH levels of healthy individuals is of 1.2658 units/mL.

Use the distance formula to find DA:
