Use a t-distribution and the given matched pair sample results to complete the test of the given hypotheses. Assume the results
come from random samples, and if the sample sizes are small, assume the underlying distribution of the differences is relatively
normal. Assume that differences are computed using d = x1 – x2.
Test Ho : Ha = 0 vs Ha : Ha > Ousing the paired data in the following table:

Current Attempt in Progress
A data collection method is described to investigate a difference in means. Determine which data analysis method is more
appropriate: paired data difference in means or difference in means with two separate groups.
To measure the effectiveness of a new teaching method for math in elementary school, each student in a class getting the new
instructional method is matched with a student in a separate class on IQ, family income, math ability level the previous year, reading
level, and all demographic characteristics. At the end of the year, math ability levels are measured again.
