Assignment #3: Independent Samples T test Conduct an Independent
Samples T test to answer the questions based on the following
scenario. (Assume a non-directional research hypothesis (two-tailed
test) and a level of significance of .05) The superintendent who
collected data for Assignments 1 and 2, continued to examine the
district’s data. One question that concerned the superintendent’s
constituencies was the difference between the school performance
scores of the superintendent’s district and a neighboring district
that had similar demographic and socio-economic...
