You wish to test the following claim (H1H1) at a significance level of =0.10=0.10. Ho:=82.7Ho:=82.7 H1:82.7H1:82.7 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data:

data

112

90.5

120.9

99.1

1) What is the test statistic for this sample? (Round intermediate values to 2 decimal places. Report answer accurate to three decimal places.) test statistic = 2) What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = 3) The p-value is...

• less than (or equal to)
• greater than

4) This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null

5) As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 82.7.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 82.7.
• The sample data support the claim that the population mean is not equal to 82.7.
• There is not sufficient sample evidence to support the claim that the population mean is not equal to 82.7.
