# Question: Ha 1 2 The null hypothesis is H0 1

Ha: μ1 ≠ μ2

The null hypothesis is H0: μ1 = μ2 and the alternative hypothesis is as specified. We have provided data from a simple random paired sample from the two populations under consideration. In each case, use the paired t-test to perform the required hypothesis test at the 10% significance level.
