Homework: HW 5 Save Score: 0 of 1 pt 5 of 26 (5 complete) HW Score: 15.38%, 4 of 26 pts Question Help | The test statistic of z- 1.71 is obtained when testing the claim that p> 0.3. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c.Using a significance levelof a 0.01, should we reject Ho or should we fail to reject Ho?

Explanation / Answer

17) a) This a right tailed test.

b) P-value = P(Z > 1.71)

                 = 1 - P(Z < 1.71)

                 = 1 - 0.9564 = 0.0436

c) As the P-value is greater than the alpha value (0.0436 > 0.01), so the null hypothesis is not rejected.

19) a) It is a two-tailed test.

   b) P-value = 2 * P(Z > 1.33)

                     = 2 * (1 - P(Z < 1.33))

                     = 2 * (1 - 0.9082)

                     = 0.1836

c) As the P-value is greater than the alpha value (0.1836 > 0.10), so the null hypothesis is not rejected.
