Decide whether each (a) confidence interval indicates that you should reject Ho Explain your reasoning 40 (b) u 41 Ho: 243 40 (a) Choose the correct answer below. O A. Fail to reject Ho. The confidence interval includes values less than 43 O B. Reject Ho. The confidence interval includes values greater than 43. O C. Fail to reject Ho. The confidence interval includes values greater than 43. O D. Reject Ho. The confidence interval includes values less than 43 41 41 42 41.5 H 45.5 44 H 45 45 45 46 46

Explanation / Answer

H0 : > = 43

(A) 44 < <45

so that region is under Null Hypothesis region. So, we failed to reject the null hypothesis. The confidence intervel includes value greater than 43.

Option C is correct.

(b) 40 < < 41

so, that region is not under null hypothesis region. So, we can reject the null hypothesis and The confidence interval is located to the left of 43.

so , Option A is correct.

(c) 41.5 < < 45.5

so, that region consists the null hypothesis region. so we can not reject the null hypothesis and the confidence interval includes values greater than 43.

Option C is correct.
