Question: Basic Computation: Testing , s Unknown A random sample of 25 values is drawn from a moundshaped and symmetric distribution. The sample mean is 10

Basic Computation: Testing μ, s Unknown A random sample of 25 values is drawn from a moundshaped and symmetric distribution. The sample mean is 10 and 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 is 9.5.

(a) Check Requirements Is it appropriate to use a Student’s t distribution? Explain. How many degrees of freedom do we use?

(b) What are the hypotheses?

(c) Compute the t value of the sample test statistic.

(d) Estimate the P-value for the test.

(e) Do we reject or fail to reject H0?

(f) Interpret the results.
