Question 1166032
Ho: prob is 0.65
Ha: prob is not 0.65
alpha P(reject Ho|Ho true}=0.01
test stat is a 1 sample proportion z=(p hat - p)/sqrt (p*(1-p)/n)
critical value is |t|>2.576
calculation is z=(0.6667-0.65)/sqrt (0.65*0.35/60)
=0.27
fail to reject Ho, and the results are consistent with the claim that the true proportion is 0.65
