Given two dependent random samples with the following results:
Population 1 | 59 | 57 | 77 | 60 | 59 | 64 | 72 | 67 |
---|---|---|---|---|---|---|---|---|
Population 2 | 61 | 53 | 84 | 53 | 69 | 74 | 64 | 73 |
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=0.01α=0.01 for the test. Assume that both populations are normally distributed.
