The University is trying to decide whether to implement a mandatory remedial math course for students with low test scores upon admissions. Historically, students with low admissions test scores have failed their first math course 61% of the time. A random sample of students with low scores is selected and assigned to a remedial math course. These students are tracked and it is found that 102 out of 175 of them still fail their first regular math course.

If the hypotheses are

H₀: p = 0.61 H_A: p < 0.61

what is the p-value for this test?

Solutions

Expert Solution

We have for given example,
Population proportion value is =0.61
x=102

n=175

Estimate for sample proportion =0.5829

Z test statistic formula for proportion

=-0.74

P value =0.2297.....................by using Z table or Excel for left tailed test =NORMSDIST(-0.74)

A researcher conducts a study of college students to decide whether they like math classes. They get a list of students with land-line phone numbers from their University and call the first 25 students, all of whom are English majors, on the list. They ask those students “Which is the worst class you’ve had on campus – your math class or another class?” 18 out of 25 say math, so the researcher concludes that students choose English majors because they...

In math course of this semester, there are 26 students and six of them are women. (a) How many ways are there to select a group of four students from math course students so that there is at least one women in the group? (b) If I randomly select a group of four, what is the probability that the group has women only? (c) I randomly choose a group of four out of 26 students. Then, again, I choose randomly...

A company is trying to decide whether to bid for a certain contract or not.

Once “short-listed” the company will have to supply further detailed information (entailing costs estimated at $5000). After this stage their bid will either be accepted or rejected. The...

The dean of the School of Fine Arts is trying to decide whether to purchase a copy machine to place in the lobby of the building. The machine would add to student convenience, but the dean feels compelled to earn an 10 percent return on the investment of funds. Estimates of cash inflows from copy machines that have been placed in other university buildings indicate that the copy machine would probably produce incremental cash inflows of approximately $16,500 per year....
