Question

Consider the following hypothesis test. Given that n = 79, = 7, x = 45.1, and
= 0.05, complete parts a through
H0: ≤43 HA: >43
a. State the decision rule in terms of the critical value(s) of the test statistic.
Reject the null hypothesis if the calculated value of the test statistic, (1)
the critical value(s), . Otherwise, do not reject the null hypothesis.
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
b. State the calculated value of the test statistic.
(3) = (Round to two decimal places as needed.) c. State the appropriate p­value.
p­value = (Round to three decimal places as needed.)
d. State the conclusion.
