6. Students in one statistics course need to earn a grade of at least C, otherwise they need to repeat the course. It is also known that 85% of all students who attend class regularly will earn a grade of at least C, while only 30% of those students who do not attend class regularly will earn a grade of at least C. Historically, 80% of all students in this course attend class regularly. You must explicitly define any events...
Archie is taking a course in probability theory. Discussion sessions with the dass TA (teaching assistant) conflict with Archie's trips to the beach. Archie has to decide between attending TA sessions, which might help him do better in the probability course, and going to the beach. Archie learns that 83% of past students who did not attend TA sessions received a grade of B or below in the course. Archie also learns that 9% of past students received a grade...

5. North Carolina State University posts the complete grade distributions for its courses online. The distribution of grades for all students in all sections of Accounting 210 in the spring semester of 2001 was Grade Probability .18 32 34 09 07 a. Using the scale A -4, B-3, C-2, D- 1, and F 0, let Xbe the grade of a randomly chosen b. Let X denote the mean grade for a random sample of 50 students from Accounting 210. Since...

Of the students living in the dormitories at a university, 65% live in the west hall, and the rest at the south tower. A sandwich shop randomly mails a coupon for a free sandwich to 27 % of those at the west hall, and to 16% of those living at the south tower. Let D be the event that the person receives a coupon, E1 be the event that the person is living in the west hall, and E2 be...
