The p-value for testing a hypothesis of

H0: μ=100

Ha: μ≠100

is 0.064 with a sample size of n= 50. Using this information, answer the following questions.

(a) What decision is made at the α= 0.05 significance level?

(b) If the decision in part (a) is in error, what type of error is it?

(c) Would a 95% confidence interval forμcontain 100? Explain.

(d) Suppose we took a sample of size n= 200 and found the exact same value of ̄x and s. How would this change the p-value of the test?

For the following hypothesis test, where H0: μ ≤ 10; vs. HA: μ > 10, we reject H0 at level of significance α and conclude that the true mean is greater than 10, when the true mean is really 14. Based on this information, we can state that we have: Made a Type I error. Made a Type II error. Made a correct decision. Increased the power of the test.
