Assume that the heights of men are normally distributed. a random sample of 16 men have a mean height of 67.5 inches and a standard deviation of 3.2 inches. construct a 99% confidence interval for the population standard deviation, σ. (2.2, 5.4) (2.2, 6.0) (1.2, 3.2) (2.2, 5.8)

(2.2, 5.8)

Step-by-step explanation:

The confidence interval for standard deviation is given by :-

Given :  Sample size : 16

Mean height : inches

Standard deviation : inches

Significance level :

Using Chi-square distribution table ,

Then , the 99% confidence interval for the population standard deviation is given by :-

i will pick c put check it over to be sure

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
