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

Expert Answer

Step 1

In this context, the aim is to test whether there is any significant difference in the population means by using the hypothesis H0:µ1 = µ2 against Ha:µ1 > µ2.

The test hypotheses are,

Null hypothesis: H0:µ1 = µ2

Alternative hypothesis: Ha:µ1 > µ2

The level of significance is α=0.10.

Step 2

The difference di=X1–X2  for each sample is obtained as follows:
