Which statement below describes a property of the t statistic of
the one-sample t test?
A.
The distribution of the t statistic (t distribution) under
H0 has a smaller (i.e. more narrow) spread than
a standard normal distribution.
B.
The distribution of the t statistic (t distribution) under
H0 depends on n.
C.
The distribution of the t statistic (t distribution) under
H0 cannot be estimated unless n is
large.
D.
Both A and B.

A sample has a mean of M = 60 and a t statistic of t = 4.5. For
a one-tailed hypothesis test with α = .01, what is the
correct statistical decision for this sample? Why?
a.
The researcher can reject the null hypothesis with α =
.05 but not with α = .01.
b.
The researcher can reject the null hypothesis with either
α = .05 or α = .01.
c.
The researcher must fail to reject the null...

statistic of t = –2.15. Which of the following decisions is
justified for a two-tailed test? (Hint: use the proper table to
find the critical values).
