Question

At a certain college, it is estimated that at most 24% of the students ride bicycles to class. Does this seem to be a valid estimate if, in a random sample of 81 college students, 24 are found to ride bicycles to class? Use a 0.01 level of significance.

Identify the null and alternative hypotheses OB. Ho: p=0.24 Hip#0.24 O A. Ho: p<0.24 Hy: = 0.24 OD. Ho: P+0.24 H: p= 0.24 0 C. Ho: p> 0.24 H:p=0.24 05. Hp: p = 0.24 H:p>0.24 O E. Ho: p=0.24 H:p<0.24 Identify the critical region. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. Z> OB. z< or z> OC. z< Find the test statistic z= (Round to two decimal places as needed.) What is the appropriate conclusion for this test? O A. Do not reject H, and conclude that there is sufficient evidence that more than 24% of the students ride bicycles to class. Thus, there is not sufficient evidence to reject the estimate that at most 24% of the students ride bicycles to class. OB. Reject H, and conclude that there is sufficient evidence that more than 24% of the students ride bicycles to class. Thus, there is sufficient evidence to reject the estimate that at most 24% of the students ride bicycles to class. OC. Do not reject Ho and conclude that there is not sufficient evidence that more than 24% of the students ride bicycles to class. Thus, there is not sufficient evidence to reject the estimate that at most 24% of the students ride bicycles to class. OD. Reject H, and conclude that there is not sufficient evidence that more than 24% of the students ride bicycles to class. Thus, there is not sufficient evidence to reject the estimate that at most 24% of the students ride bicycles to class.
