A random sample of 100 observations is selected from a binomial population with unknown probability of success, p. The computed value of p is equal to 0.71. Complete parts a through e. a. Test Ho: p = 0.61 against Ha: p > 0.61. Use a = 0.01. Find the rejection region for the test. Choose the correct answer below. O A. z 2.33 O B. z 2.575 O c. z 2.575 O E. Z 2.33 Calculate the value of the test statistic. z= (Round to two decimal places as needed.) Make the appropriate conclusion. Choose the correct answer below. O A. Reject Ho- There is insufficient evidence at the o = 0.01 level of significance to conclude that the true proportion of the population is greater than 0.61. O B. Do not reject Ho. There is insufficient evidence at the a = 0.01 level of significance to conclude that the true proportion of the population is greater than 0.61. O C. Do not reject Ho. There is sufficient evidence at the a= 0.01 level of significance to conclude that the true proportion of the population is greater than 0.61. O D. Reject Ho. There is sufficient evidence at the a= 0.01 level of significance to conclude that the true proportion of the population is greater than 0.61. b. Test Ho: p= 0.61 against Ha- P > 0.61. Use a = 0.10.
