Answer: The following MINITAB output presents the results
Chapter 6, Problem 12E(choose chapter or problem)
The following MINITAB output presents the results of a hypothesis test for a population proportion p.
a. Is this a one-tailed or two-tailed test?
b. What is the null hypothesis?
c. Can \(H_{0}\) be rejected at the 2% level? How can you tell?
d. Someone asks you whether the null hypothesis \(H_{0}: p \geq 0.45\) versus \(H_{1}: p<0.45\) can be rejected at the 2%
level. Can you answer without doing any calculations? How?
e. Use the output and an appropriate table to compute the P-value for the test of \(H_{0}: p \leq 0.25\) versus \(H_{1}: p>0.25\).
f. Use the output and an appropriate table to compute a 90% confidence interval for p.
