2019242326232524262620192423262325242626
Test to determine if we can infer at the 7% significance level that the population mean is not equal to 22, filling in the requested information below.
A. The value of the standardized test statistic:
Note: For the next part, your answer should use interval notation. An answer of the form (−∞,?)(−∞,a) is expressed (-infty, a), an answer of the form (?,∞)(b,∞) is expressed (b, infty), and an answer of the form (−∞,?)∪(?,∞)(−∞,a)∪(b,∞) is expressed (-infty, a)U(b, infty).
B. The rejection region for the standardized test statistic:
C. The p-value is
D. Your decision for the hypothesis test:
A. Reject ?0H0.
B. Do Not Reject ?0H0.
C. Do Not Reject ?1H1.
D. Reject ?1H1.
