Why Do You Think Mr. Baird Believes That Ap Stats?
Ap Stats:
76% of Naperville students have been alcohol free in the last 30 days. Mr. Baird believes that AP stats students are different.
Write the hypothesis statements for his belief. Assume a= .1
Some of his students take a random sample of students and comes with a 90% CI of (.80, .90)
Based on these results, what will the results of Mr. Baird’s test be? Explain.
H0: p=.76
Ha=p=/=.76
Your answer should include:
Reference that a 90% Confidence interval corresponds to a 2 sided test with a =.1
Indicating that the interval does not include .76
Diagram tends to help with explanationaaaaaaaaaaaaaaaaaaaaaaa
Test statistic = (statistic – parameter)/(standard deviation of statistic) t = (xbar-unot)/(sx/sqrt(n)) from example
