Question 1:
a) A statistics practitioner wants to test the following hypotheses:
Ho: p=.70
H1: p> .70
A random sample of 100 produced B (beta) =.73
Calculate the p-value of the text.
b) Repeat part a with p = .72
c) Repeat part a with p = .71
d) Describe the effect on the z-statistic and its p-value of decreasing the sample proportion.
Question 2:
Determine the sample size necessary to estimate a population proportion to within .01 with 90% confidence assuming you have no knowledge of the approximate value of the sample proportion.
