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 :-

y/x of point b= y/x of point a
