Question

You wish to test the following claim (HaHa) at a significance level of α=0.002α=0.002.

      Ho:μ=90.3Ho:μ=90.3
      Ha:μ≠90.3Ha:μ≠90.3

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=27n=27 with mean M=102.6M=102.6 and a standard deviation of SD=17.7SD=17.7.

1. What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value = ___

2. The p-value is...

• less than (or equal to) αα
• greater than αα

3. This p-value leads to a decision to...

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

4. 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 90.3.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 90.3.
• The sample data support the claim that the population mean is not equal to 90.3.
• There is not sufficient sample evidence to support the claim that the population mean is not equal to 90.3.
