UCF administrators want to determine the proportion of students who have seen The Matrix. If the proportion differs from 60%, then the university will be forced to permanently close. Suppose a hypothesis test is conducted and the test statistic is -1.23. If α = 0.25, what is the most appropriate decision and reasoning?

Answer #1

Critical value = + Z0.125 = +1.15 = -1.15 , 1.15

Since test statistic < -1.23, we should reject the null hypothesis.

In the past, 60% of all undergraduate students enrolled at State University earned their degrees within four years of matriculation. A random sample of 95 students from the class that matriculated in the fall of 2014 was recently selected to test whether there has been a change in the proportion of students who graduate within four years. Administrators found that 40 of these 95 students graduated in the spring of 2018 (i.e., four academic years after matriculation). Given the sample...

As of 2012, the proportion of students who use a MacBook as their primary computer is 0.37. You believe that at your university the proportion is actually different from 0.37. The hypotheses for this test are Null Hypothesis: p = 0.37, Alternative Hypothesis: p ≠ 0.37. If you randomly select 29 students in a sample and 13 of them use a MacBook as their primary computer, what is your test statistic and p-value?

A college instructor claims that the proportion of students who will fail the final exam is less than 10%.     To test this claim, a random sample of student results on the final exam is monitored. Assume that the test statistic for this hypothesis test is −2.13. Assume the critical value for this hypothesis test is −1.645. Come to a decision for the hypothesis test and interpret your results with respect to the original claim. Select the correct answer below: a)...
