10. The institutional researcher at a community college reads that the persistence rate (percent of students who return to college for the next academic year) is higher for full-time students as compared to part-time students. He decides to test this out at his college. He tracks a randomly selected randomly selected sample of 350 full- time students and 480 part-time students. Of the 350 full-time students, 316 return to college the next year. Of the 480 part-time students, 319 return to college next year. Conduct an appropriate hypothesis test at 5% significance level. Show all steps carefully, including a well-labeled graph showing your p-value.

a. State and describe the appropriate parameter(s).

b. State the hypotheses.

c. State the Type I and Type II errors in context.

d. State and describe the appropriate random variable. e. State the test statistic and the p-value.

f. Sketch an accurate and fully labeled graph showing the p-value.

g. Make the decision and state the conclusion in the context of the problem.

The college board claims that 32% of community college students take five semesters to complete a two-year program. In a survey of 1400 randomly selected community college students enrolled in a two-year program, 401 of them took five semesters to complete their two-year program. Test the college board's claim at a level of significance of 0.01. Calculate the test statistics associated with this hypothesis. (Round your answer to 2 decimal places) Calculate the P-Value associated with the test statistics that...

Throughout the country, the proportion of first-time, first-year community college students who return for their second year of studies is p = 0.52 according to the Community College Survey of Student Engagement. Suppose a community college institutes new policies geared toward increasing student retention. The first year this policy was in place there were n = 2843 first-time, first-year students (N = 1, 050,000). Of these students, x = 1516 returned for their second year of studies. Treat these students...

10) We conduct a study to determine whether the majority of community college students plan to vote in the next presidential election. We choose a significance level of 0.05. We survey 650 randomly selected community college students and find that 54% of them plan to vote. The P-value is 0.02. H0: 50% of community college students plan to vote in the next presidential election. Ha: More than 50% of community college students plan to vote in the next presidential election....

Professor Meanie’s persistent rate (i.e. students who do not drop the course) is historically 65%. However, this semester he decided to “flip” his classroom. Instead of coming to class for a typical lecture, students are expected to watch the lecture online the night before. The next day students will work in groups of three on exercises that reinforce concepts from the video lectures. He started with 120 students and 72 completed the course. Ideally, he is trying to increase the...

Is there any systematic tendency for part-time college faculty to hold their students to different standards than do full-time faculty? An article reported that for a sample of 125 courses taught by full-time faculty, the mean course GPA was 2.7186 and the standard deviation was 0.67342, whereas for a sample of 88 courses taught by part-timers, the mean and standard deviation were 2.8439 and 0.52241, respectively. Does it appear that true average course GPA for part-time faculty differs from that...

In a particular year, 68% of online courses taught at a system of community colleges were taught by full-time faculty. To test if 68% also represents a particular state's percent for full-time faculty teaching the online classes, a particular community college from that state was randomly selected for comparison. In that same year, 35 of the 44 online courses at this particular community college were taught by full-time faculty. Conduct a hypothesis test at the 5% level to determine if...

The Dean of the College of Liberal Arts and Sciences (CLAS) reported that the mean time for CLAS students to complete their degree at CU-Denver is less than 5 years. She randomly selected a sample of 25 recent CLAS graduates and found that their mean time to graduate was 4.75 years with a sample standard deviation of 0.8 years. At an α = 0.1 level, is their sufficient evidence to conclude that the mean time for CLAS students to complete...
