Question
You wish to test the following claim (Ha) at a significance level of a = 0.05.
H.:µ = 84.3
Ha:µ + 84.3
You believe the population is normally distributed, but you do not know the standard deviation. You obtain
a sample of size 'n= 15 with a mean of M = 70.4 and a standard deviation of SD = 17.4.
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 =

As such, the final conclusion is that...
O There is sufficient evidence to warrant rejection of the claim that the population mean is not equal
to 84.3.
O There is not sufficient evidence to warrant rejection of the claim that the population mean is not
equal to 84.3.
The sample data support the claim that the population mean is not equal to 84.3.
O There is not sufficient sample evidence to support the claim that the population mean is not equal
to 84.3.
