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...
O less than (or equal to) a
O greater than a
Transcribed Image Text: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 population mean is less than
90.9.
O There is not sufficient evidence to warrant rejection of the claim that the population mean is less
than 90.9.
O The sample data support the claim that the population mean is less than 90.9.
O There is not sufficient sample evidence to support the claim that the population mean is less than
90.9.
