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

Ho:=90.1

Ha:90.1

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of sizen=348with a mean ofM=90.8and a standard deviation ofSD=17.8

What is the critical value for this test? (Report answer accurate to three decimal places.)

critical value =

What is the test statistic for this sample? (Report answer accurate to three decimal places.)

test statistic =

The test statistic is...

• in the critical region
• not in the critical region

This test statistic leads to a decision to...

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

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 90.1.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 90.1.
• The sample data support the claim that the population mean is not equal to 90.1.
• There is not sufficient sample evidence to support the claim that the population mean is not equal to 90.1.
