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 reject the claim that the population mean is not
equal to 90.7.
There is not sufficient evidence to reject the claim that the population mean is
not equal to 90.7.
There is sufficient evidence to support the claim that the population mean is not
equal to 90.7.
There is not sufficient sample evidence to support the claim that the population
mean is not equal to 90.7.
