The p-value is...
79
71.4
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
O less than (or equal to) a
O greater than a
What is the p-value for this sample? For this calculation, use the degrees of freedom reported from the
technology you are using. (Report answer accurate to four decimal places.)
p-value=

69.2
70.7 85.8
79.4
72.2
76.4 86.8
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 first population mean is less
than the second population mean.
O There is not sufficient evidence to warrant rejection of the claim that the first population mean is
less than the second population mean.
O The sample data support the claim that the first population mean is less than the second population
mean.
O There is not sufficient sample evidence to support the claim that the first population mean is less
than the second population mean.
