At a certain college, it is estimated that at most 20% of the students ride bicycles to class. Does this seem to be a valid estimate if, in a random sample of 84 college students, 24 are found to ride bicycles to class? Use a 0.05 level of significance Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. .. Let a success be a student that rides a bicycle to class. Identify the null and alternative hypotheses. O A. Ho: p=0.2 H:p<0.2 OB. Ho:p>0.2 Hy: p=0.2 O E. Ho: p*0.2 H:p=0.2 0 C. Họ p= 0.2 Hip+0.2 OE. Hop = 0.2 H:p>0.2 OD. Ho: p<0.2 Hy: p=0.2 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 20% of the students ride bicycles to class. Thus, there is sufficient evidence to reject the estimate that at most 20% of the students ride bicycles to class. OB. Reject H, and conclude that there is not sufficient evidence that more than 20% of the students ride bicycles to class. Thus, there is sufficient evidence to reject the estimate that at most 20% of the students ride bicycles to class. OC. Do not reject H, and conclude that there is not sufficient evidence that more than 20% of the students ride bicycles to class. Thus, there is not sufficient evidence to reject the estimate that at most 20% of the students ride bicycles to class. OD. Reject H, and conclude that there is sufficient evidence that more than 20% of the students ride bicycles to class. Thus, there is sufficient evidence to reject the estimate that at most 20% of the students ride bicycles to class.
