The thicknesses of 96 96 randomly selected linoleum tiles were found to have a variance of 3.07 3.07 . Construct the 95% 95 % confidence interval for the population variance of the thicknesses of all linoleum tiles in this factory. Round your answers to two decimal places.
Homework Answers
n = 96
s2 = 3.07
= 0.05
ndf =n - 1 = 96 - 1 = 95
