You wish to test the following claim (HaHa) at a significance level of ?=0.10?=0.10.

      Ho:?=63.8Ho:?=63.8
      Ha:?<63.8Ha:?<63.8

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=13n=13 with mean M=60.9M=60.9 and a standard deviation of SD=11.8SD=11.8.

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) ?? or greater than ??


This test statistic leads to a decision to...

reject the null, accept the null, or fail to reject the null



As such, the final conclusion is that...

A.) There is sufficient evidence to warrant rejection of the claim that the population mean is less than 63.8.

B.) There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 63.8.

C.) The sample data support the claim that the population mean is less than 63.8.

D.)There is not sufficient sample evidence to support the claim that the population mean is less than 63.8.

Homework Answers

Answer #1

Test statistic t = (M - )/(s/)

                      = (60.9 - 63.8)/(11.8/)

                      = -0.886

P-value = P(T < -0.886)

             = 0.1965

The P-value is greater than the significance level.

This test statistic leads to a decision to fail to reject the null.

Option - D is correct.
