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 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.
