Question
A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the
required hypothesis test about the mean, p, of the population from which the sample was drawn. Use the critical-
value approach.
Sample mean = 3.13
s = 0.59
n = 9
a = 0.01
%3D
Ho: H = 2.85
H1: µ > 2.85
1. The test statistics is
(Round to three decimal places)
2. The critical value(s) is/are
(If there are two critical values separate each with a comma.)
3. The decision is to
the null hypothesis. (Enter R if you reject and enter F if you fail to reject)
