Research Question
: Is there enough statistical evidence to suggest that the Minneapolis Public
School District is doing worse than the 25% benchmark for urban schools?

b.
Compute the appropriate pvalue for this problem. (2 pt)
The appropriate pvalue for these 1000 trials is (15+7+6+1+1)/1000 = 30/1000 = .03 = 3%. I found this by
adding all of the numbers of trials that had 14 or less schools making AYP then dividing by the amount of
trials, which was 1000.
c.
Answer the research question using the outcomes from your simulation study.
Explain. (3 pts)
Yes. The pvalue for my 1000 trials (.03 or 3%) is less than the appropriate estimated pvalue of .05 or 5%.
Because the pvalue is less than .05, statisticians would say that there is enough statistical evidence to
support the claim that the Minneapolis Public School District is underperforming.
This is the end of the preview.
