Question
You wish to test the following claim (Ha) at a significance level of a = 0.001.
H.:µ = 79.1
Ha:u < 79.1
You believe the population is normally distributed, but you do not know the standard deviation. You
obtain a sample of size n = 581 with a mean of M = 77.9 and a standard deviation of
SD = 11.7.
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
O not in the critical region
This test statistic leads to a decision to...
O reject the null
O accept the null
O fail to reject the null

As such, the final conclusion is that...
O There is sufficient evidence to warrant rejection of the claim that the population mean is less
than 79.1.
O There is not sufficient evidence to warrant rejection of the claim that the population mean is
less than 79.1.
O The sample data support the claim that the populațion mean is less than 79.1.
O There is not sufficient sample evidence to support the claim that the population mean is less
than 79.1.
