IGNORE SELECTED ANSWERS

Consider a one-sided right-tailed hypothesis test concerning the mean mu_0 from a normal population, with sample size n = 28, standard deviation s, and a = 0.001. Explain the error in each of the following statements. a. The test statistic is T = X - mu_0/sigma/Squareroot 28. The test statistic should be T = X - mu_0/sigma/Squareroot 27. The test statistic should be T = X - mu_0/s/Squareroot 27. The test statistic should be T = X - mu_0/s/Squareroot 28. There is no enough data to find the test statistic. b. The rejection region is RR: T greaterthanorequalto 3.69. The reject region should be: |T+ greaterthanorequalto 3.408. The reject region should be: T greaterthanorequalto 3.421. The reject region should be: T greaterthanorequalto 3.674. The reject region should be: T greaterthanorequalto 2.473. c. If the value of the test statistic is t = 2.517, then p
