(Report answer accurate to three decimal places.) test statistic = 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 =
The p-value is...
O less than (or equal to) a
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...
O There is sufficient evidence to warrant rejection of the claim that the first population mean is
greater than the second population mean.
O There is not sufficient evidence to warrant rejection of the claim that the first population mean is
greater than the second population mean.
O The sample data support the claim that the first population mean is greater than the second
population mean.
There is not sufficient sample evidence to support the claim that the first population mean is greater
than the second population mean.
