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

  Observation from
Pair Population 1 Population 2
1 13 11
2 16 15
3 13 10
4 14 8
5 12 8
6 8 9
7 17 14



Expert Answer

Step 1

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
