Given two dependent random samples with the following results:
| Population 1 | 6060 | 7474 | 6666 | 7373 | 6868 | 6969 | 8181 | 6767 |
|---|---|---|---|---|---|---|---|---|
| Population 2 | 6969 | 7070 | 7575 | 6868 | 7171 | 7171 | 7272 | 6969
Can it be concluded, from this data, that there is a significant difference between the two population means? Let d=(Population 1 entry)−(Population 2 entry)d=(Population 1 entry)−(Population 2 entry). Use a significance level of α=0.02α=0.02 for the test. Assume that both populations are normally distributed. Copy Data Step 1 of 5 : State the null and alternative hypotheses for the test. |
