Comment: That null hypothesis is unacceptable. Ho MUST contain
equality.
---------------------------------------
Given that the sample mean is 50.5 and s = 5.0, answer the following questions:
(A) What is the computed value of the test statistic?
t(50.5) = (50.5-50)/[5/sqrt(45)
---------------------------------------
(B) What distribution does the test statistic have when the null hypothesis is true?
---
mean = 50 ; std = 5/sqrt(45)
-----------------------------------------
(C) Is the alternative hypothesis one-tailed or two-tailed?
one-tail
-----------------------------
(D) What is the p-value?
p-value = P(t > the test statistic, with df=44)
