Suppose a researcher wants to make sure that the probability of committing a Type I error is less than 5%. How can the researcher control for this?A. Set the value for a Type II error at 0.05.
B. Set the alpha level at 0.05.
C. Place the rejection region in both tails.
D. Both setting the alpha level at 0.05 and placing the rejection region in both tails.

Answers

Answer:

B. Set the alpha level at 0.05.

Step-by-step explanation:

Hypothesis testing is a procedure whereby a researcher determines if the null hypothesis is rejected or accepted, depending on the significant level or the alpha level. When a type I error is made, the null hypothesis is rejected even though it is correct. To solve this problem, the significant or alpha level is set to 5% or 0.05.

Linda is playing a game. On each turn that she takes, she can earn 2 points or 3 points. She has taken 16 turns and has earned a total of 34 points. On how many turns has Linda earned 2 points?

Answers

Answer:

Linda earned 2 points on 14 turns.

Step-by-step explanation:

Given that Linda has played 16 turns and has obtained 34 points, taking into account that in each turn she can obtain 2 or 3 points, to determine the number of turns in which she obtained 2 points, the following table must be performed:

-If in 16 turns she obtained 2 points, the total points will be 32

-If in 15 turns she obtained 2 points and in 1 turn she obtained 3 points, the total points will be 33

-If in 14 turns she obtained 2 points and in 2 turns she obtained 3 points, the total of points will be 34

Therefore, Linda scored 2 points in 14 of the 16 turns played.

Answer:

21 boys

Step-by-step explanation:

2:3=14:x you cross multiply this to find the amount of boys

2x=42

x=21

There are 21 boys in the class.

Basically, solve what you have there with cross-multiplication.

2x = 14 x 3

2x = 42

Then divide both sides by 2. (edited it bc didn't say what you actually had to do)

2x ÷ 2 = 42 ÷ 2

x = 21.

There are 21 boys in the class.

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what percentage of IQ scores are at least 59? Please do not round your answer.

Answers

Answer:

1.35%

Step-by-step explanation:

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what ? Please do not round your answer.

Empirical rule formula states that:

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

We don't know the number of Standard deviation yet , hence:

Mean = 104

Standard deviation = 15.

At least 59

Hence:

104 - 15x = 59

104 - 59 = 15x

45 = 15x

x = 45/15

x = 3

Hence, At least 59 is 3 standard deviations away from the mean on one side of the distribution thus,

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

100% - 99.7%

= 0.003

Since it is on one side of the distribution:

= 1.5% - 0.3%

= 0.015 - 0.0015

= 0.00135

Converting to percentage

= 1.35%

The percentage of IQ scores that are at least 59 is 1.35%

The cost to manufacture a product is proportional to the quantity produced, with a cost of $35000 dollars per day when 700 items are produced. The cost to store n items is proportional to the square of n, with a daily storage cost of $3430 dollars when 700 items are stored. In addition, there is a fixed daily cost of $7000. The total daily cost, T when producing and storing n items is the sum of production, storage and fixed costs.

Write a formula for T as a function of n.

Answers

Solution :

[tex]$T_1$[/tex] = k.n (cost proportional to quantity)

35000 = k . 700

k = [tex]$\frac{35000}{700}$[/tex]

  = 50

So [tex]$T_1$[/tex] = 50 n

Now [tex]$T_2=Pn^2$[/tex]     (cost proportional to square of n)

[tex]$3430= P(700)^2$[/tex]

3430 = 490000 P

[tex]$P = \frac{3430}{490000}$[/tex]

[tex]$P = \frac{7}{1000}$[/tex]

[tex]$T_2=\frac{7}{1000}n^2$[/tex]

Now, [tex]$T_3= 7000$[/tex]   (fixed)

Therefore,

Total, [tex]$T=T_1+T_2+T_3$[/tex]

[tex]$T=50n+\frac{7}{1000}n^2+7000$[/tex]

[tex]$T=0.007n^2+50n+7000$[/tex]

The required formula in terms of T and n is T = 0.000[tex]n^{2}[/tex] + 50 n +7000.

Given that ,

The total daily cost = T

When producing and storing n items is the sum of production, storage and fixed costs.

The manufacturing cost of a product when 700 items produced = $35000 dollars per day.

Daily storage cost of when 700 items are stored = $3430 dollars

We have write the formula in terms of total daily cost T and n stored items.

According to the question,

The cost to manufacture a product is proportional to the quantity produced, with a cost of $35000 dollars per day when 700 items are produced.

Where ,total daily cost T and n stored items.

[tex]T_1 = k . n[/tex]

$35000 =  k.700

[tex]k = \frac{35000}{700}[/tex]

k = $50

The cost to store n items is proportional to the square of n, with a daily storage cost of $3430 dollars when 700 items are stored.

[tex]T_2 = pn^{2}[/tex]

$3430 = P [tex](700)^{2}[/tex]

$3430 = P 490000

[tex]P = \frac{3430}{490000} \\\\P = \frac{7}{1000}[/tex]

There is a fixed daily cost of $7000.

[tex]T_3 = 7000[/tex]

Combine all the equation ,

Where T = [tex]T_1 = T_2 = T_3[/tex] and p = k =n

T = 0.000[tex]n^{2}[/tex] + 50 n +7000

Hence,  The required formula in terms of T and n is T = 0.000[tex]n^{2}[/tex] + 50 n +7000.
