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

Ho:μ=67.7
Ha:μ>67.7

You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data:

data
75.9
71.2
85.3
73.9

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... (multiple choice)

less than (or equal to) αα

greater than αα

This test statistic leads to a decision to... (multiple choice)

reject the null

accept the null

fail to reject the null

As such, the final conclusion is that... (multiple choice)

There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 67.7.

There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 67.7.

The sample data support the claim that the population mean is greater than 67.7.
