Hoμ
H : μ > 84.7
You believe the population is normally distributed, but you do not know the standard deviation. You obtain
a sample of size n = 101 with mean M = 86.7 and a standard deviation of SD = 11.7.
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...
less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O 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 greater
than 84.7.
○ There is not sufficient evidence to warrant rejection of the claim that the population mean is
greater than 84.7.
○ The sample data support the claim that the population mean is greater than 84.7.
○ There is not sufficient sample evidence to support the claim that the population mean is greater
than 84.7.
