Question

2. We wish to test $H_0: \mu = 20$ versus $H_a: \mu \neq 20$. A random sample of 9 observations from a normally distributed population yielded a test statistic of 2.14. We do not know the population standard deviation. The $p$-value for this test is A. 0.0162. B. between 0.05 and 0.10. C. between 0.025 and 0.05. D. 0.0324 E. between 0.01 and 0.02.
