Question
A different random sample with 220 in-person voters was collected, and the value of the test statistic based on this sample was -2.57. What is the appropriate conclusion to the hypothesis test
at an a = 0.01 level ?
O a. Fail to reject H0. There is sufficient evidence to conclude that the proportion of all in-person voters who waited in line for more than two hours has now fallen below 0.23.
O b. Fail to reject H0. There is not sufficient evidence to conclude that the proportion of all in-person voters who waited in line for more than two hours has now fallen below 0.23.
O c. Reject HO. There is sufficient evidence to conclude that the proportion of all in-person voters who waited in line for more than two hours has now fallen below 0.23.
O d. Reject H0. There is sufficient evidence to conclude that the state government's new streamlined voting scheme reduced the number of in-person voters who waited in line for more than
two hours below 0.23.
O e. Reject HO. There is sufficient evidence to conclude that the proportion of the 220 in-person voters sampled who waited in line for more than two hours has now fallen below 0.23.
