Based on historical records, in a traditional Intermediate Algebra course, 13.3% receive an A, 19.1% receive a B, 24.6% receive a C, 10.4% receive a D, 11.4% receive an F, and 21.2% receive a W. The mathematics department decided to offer a redesigned course called the Math Redesign Program (MRP). The grade distribution for the MRP course is shown below. Can you conclude that the distribution of grades in the MRP course differs from the traditional course? Use the a = 0.07 level of significance. Grade A B C D F W Frequency 23 43 59 8 34 33 a. State the null and alternative hypotheses. Ho: Select an answer v ? v Select an answer v H1 : Select an answer v ? Select an answer v b. Find the critical value and sketch the rejection region.

Find the test statistic. d. Find the p-value.e. Decide: Select an answer v H0 f. Conclusion: At or = 0.07 significance level, there Select an answer v enough evidence to conclude that the distribution of grades in the MRP course differs from the traditional course. A researcher wants to determine whether or not bicycle accidents occur equally over the days of the week. She randomly selects a sample of bicycle accidents and records the day of the week that each accident occurred. Ia-- mm Is there evidence to conclude that the accidents are more likely on some days of the week than others? Use the a = 0.04 level of signicance. a. State the null and alternative hypotheses.
