Question

You wish to test the following claim (H) at a significance level of a = 0.1.
H.:µ = 80.4
Haiu < 80.4
You believe the population is normally distributed, but you do not know the population standard deviation
You obtain a sample of sizen =
18 with a mean of M = 61.1 and a standard deviation of SD
= 20.5.
What is the critical value for this test?
critical value =
%3D
Find the critical value from the ztable (https://ma336.qccmathcs.com/ztable.html) or the
ttable(https://ma336.qccmathcs.com/ztable.html)
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
%3D
The test statistic is...
in the critical region
not in the critical region
This test statistic leads to a decision to...
reject the null
accept the null
O fail to reject the null

As such, the final conclusion is that...
There is sufficient evidence to warrant rejection of the claim that the population mean is less than
80.4.
There is not sufficient evidence to warrant rejection of the claim that the population mean is less than
80.4.
The sample data support the claim that the population mean is less than 80.4.
There is not sufficient sample evidence to support the claim that the population mean is less than
80.4.
