A different random sample with 220 in-person voters was collected, and the value of the test statistic based on this sample was -2.66. What is the appropriate conclusion to the hypothesis test at an α=0.01 level ?
Select one:
a. Reject H0. 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.
b. 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.
c. 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.
d. 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.
e. 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.

We are conducting a hypothesis test to see if less than 80% of ST 311 students are viewing the weekly asynchronous modules. Our hypotheses are H0:p=0.8
vs. HA:p<0.8
. We looked at the Moodle logs for a random sample of 122, and found that Moodle recorded 113 of these students had accessed the asynchronous modules that week.
What is the appropriate conclusion to this test at an α=0.05
significance level?
Select one:
a. We cannot perform this test because requisite assumptions have not been met.
b. We fail to reject the null hypothesis and conclude that less than 80% of ST 311 students are viewing the asynchronous modules.
c. We fail to reject the null hypothesis and cannot conclude that less than 80% of ST 311 students are viewing the asynchronous modules.
d. We reject the null hypothesis and conclude that less than 80% of ST 311 students are viewing the asynchronous modules.
e. We reject the null hypothesis and conclude that 92.62% of ST 311 students are viewing the asynchronous modules.
f. We accept the null hypothesis and conclude that 80% of ST 311 students are viewing the asynchronous modules.

To follow up on our previous hypothesis test, a random graduate student instructor is selected and inspects the Moodle logs for all students enrolled in their section, and determines the sample proportion of those 104 students that have been viewing the asynchronous modules is 0.6346. If they test the same hypotheses, what is the appropriate conclusion to a hypothesis test using this sample at the α=0.05
level ?
Select one:
a. We fail to reject the null hypothesis and cannot conclude that less than 80% of ST 311 students are viewing the asynchronous modules.
b. We fail to reject the null hypothesis and conclude that less than 80% of ST 311 students are viewing the asynchronous modules.
c. We cannot perform this test because requisite assumptions have not been met.
d. We accept the null hypothesis and conclude that 80% of ST 311 students are viewing the asynchronous modules.
e. We reject the null hypothesis and conclude that 63.46% of ST 311 students are viewing the asynchronous modules.
f. We reject the null hypothesis and conclude that less than 80% of ST 311 students are viewing the asynchronous modules
