Question

c) Find the test statistic.1 pt) Questions 8-10: Multiple choice (5 points each) 9) A test is made of Ho: = 36 versus Ha: 4. The true value of is 5, and Ho is rejected. Determine whether the outcome is a Type I error, a Type II error, or a correct decision. b) Type II error c) Correct decision a) Type I error 11) A test is made of Ho: = 86 versus HaJL 86. The true value of is 87, and Ho is not rejected. Determine whether the outcome is a Type I error, a Type II error, or a correct decision. a) Type I error b) Type II error c) Correct decision

Explanation / Answer

9) Rejection of a true null hypothesis is called a type I error

Therefore this is a case of a type I error here.

10) As we are given that true mean is 5 and therefore null hypothesis is false. Also as the null hypothesis is false and rejected, therefore correct decision is made here.

11) Here we are given that the null hypothesis is not rejected even though it is false. Therefore this is type II error.
