The null hypothesis is H 0 : 1 = 2 and the alternative hypothesis is

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.
