In Exercises, 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.

Ha: µ1 ≠ µ2

Whether there is any significant difference in the population means by using the hypothesis H0:µ1 = µ2 against Ha:µ1µ2.

The test hypotheses are,

Null hypothesis: H0:µ1 = µ2

Alternative hypothesis: Ha:µ1µ2
