Construct the confidence interval for the population standard deviation for the given values. Round your answers to one decimal place.

n=5, s=4.3, and c=0.95

Solutions

Expert Solution

Solution :

Given that,

s = 4.3

s2 = 18.49

2L = 2/2,df = 11.143

2R = 21 - /2,df = 0.484

The 95% confidence interval for is,

(n - 1)s2 / 2/2 < < (n - 1)s2 / 21 - /2

  4 * 18.49 / 11.143 < < 4 * 18.49 / 0.484

2.6 < < 12.4

(2.6 , 12.4)
