Question
You wish to test the following claim (H) at a significance level of a = 0.05.
Ho: μ = 68.9
Ha:
68.9
You believe the population is normally distributed, but you do not know the standard deviation. You obtain
a sample of size n = 7 with mean M = 82.7 and a standard deviation of SD = 9.9.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =
The p-value is...
O less than (or equal to) a
O greater than a
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 not equal
to 68.9.
O There is not sufficient evidence to warrant rejection of the claim that the population mean is not
equal to 68.9.
O The sample data support the claim that the population mean is not equal to 68.9.
O There is not sufficient sample evidence to support the claim that the population mean is not equal
to 68.9.
