Given two dependent random samples with the following results:
Population 1 | 56 | 66 | 69 | 66 | 60 | 59 | 56 | 54 |
---|---|---|---|---|---|---|---|---|
Population 2 | 65 | 64 | 74 | 64 | 63 | 64 | 54 | 60 |
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.
since test statistic does not falls in rejection region we fail to reject null hypothesis |
we do not have have sufficient evidence to conclude that there is a significant difference between the two population means |
