The students in a Math class decide to divide themselves into groups of equal size to study multiple congruencesWhen they try groups of 4, 3 are left over; groups of 5, 2 are left; finally they try groups of 7 and discover that if the professor joins in then they can use 7. The professor, reasoning that he never really understood modular arithmetic anyway, thinks it will probably do him some good and agrees to join in. What is the number of students in the class if you are told it is between 150 and 250

A small community college claims that their average class size is equal to 35 students. This claim is being tested with a level of significance equal to 0.02 using the following sample of class sizes: 42, 28, 36, 47, 35, 41, 33, 30, 39, and 48. Assume class sizes are normally distributed. (NOTE: We need to assume that class sizes are normally distributed in order to use the t distribution because the sample size n=10 < 25, and the Central...

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...

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...
