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.

Solution: The 99% confidence interval for the population standard deviation is given below:

σ

σ

σ

Step-by-step explanation:

The confidence interval for population standard deviation is given by :-

Given : n = 16

Standard deviation : s = 3.2

Significance level :

Critical values by using chi-square distribution table :-

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

Hence,  a 99% confidence interval for the population standard deviation :

$9.41
