A random sample of16values is drawn from a mound-shaped and symmetric distribution. The sample mean is10and the sample standard deviation is 2. Use a level of significance of 0.05 to conduct a two-tailed test of the claim that the population mean is9.5.(a) Is it appropriate to use a Student'stdistribution?

(d) Estimate theP-value for the test. P-value > 0.2500.

100 <P-value < 0.250

0.050 <P-value < 0.100

0.010 <P-value < 0.050

P-value < 0.010
