Discuss the below:
Q1. The confidence interval: 5.06 < sigma2 < 23.33 is for the population variance based on the following sample statistics:
n = 25, x-bar = 41.2, and s = 3.1
What is the degree of confidence? Use only integers, no % sign and no decimal places.
Q2. Find the margin of error. 95% confidence interval; n = 91 ; x-bar = 55, s = 5.4
