Assignment 4: T test for Dependent samples
Directions
Conduct a T test for Dependent Samples to answer the questions
based on the following scenario. (Assume a nondirectional research
hypothesis (two-tailed test) and a level of significance of
.05)
Scenario
To further examine the school performance scores of the
district, the superintendent identified schools within the district
that could be matched to schools from surrounding districts using a
series of demographic characteristics such as size, socio-economic
status, and percent special education...

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)
. Use a significance level of α=0.02
for the test. Assume that both populations are normally
distributed.
