You wish to test the following claim (Ha) at a significance level of a =
0.05.
Ho : μ = 88.3
Ha:μ #88.3
You believe the population is normally distributed, but you do not know the standard deviation. You obtain
a sample of size n = 119 with a mean of M = 84.4 and a standard deviation of SD = 14.1.
What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value = +
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
The test statistic is...
O in the critical region
not in the critical region
