This Question: 1 pt 2 of 5 (0 complete) Consider the hypotheses shown below. Given that x = 52, 13, n#38, -001, complete parts a and b. Ho: 49. H1:>49 a. What conclusion should be drawn? b. Determine the p-value for this test. a. The z-test statistic is (Round to two decimal places as needed.) The critical z-score(s) is(are) Round to two decimal places as needed. Use a comma to separate answers as needed.) Because the test statistic the null hypothesis b. The p-value is Round to three decimal p is greater than the critical value, does not fall within the critical values is less than the critical value falls within the critical values, Enter your answer in each of the answer boxes.

Explanation / Answer

Ans:

a)Test statistic:

z=(52-49)*sqrt(38)/13=1.42

critical z value(right tailed)=2.33

As,z=1.42 is less than the critical value of 2.33,we do not reject null hypothesis.

b)

p-value=P(z>1.42)=0.078

(without rounding off z,p-value=0.077)
