Compute the probability of passing the course given that the course
taken was calculus.
Homework Answers
We have to find the probability of passing the course given that the course taken was calculus.
That is we have to find P( Passing the course| calculus)
P( Passing the course| calculus) = P( Passing the course and calculus) / P( Calculus)
P( Passing the course and calculus) = 0.25
P(Calculus) = 0.38
P( Passing the course| calculus) = P( Passing the course and calculus) / P( Calculus)
P( Passing the course| calculus) = 0.25/0.38 = 0.6579

4. A random sample of 12 second-year university students enrolled in a business statistics course was drawn. At the course's completion, each student was asked how many hours he or she spent doing homework in statistics. The data are listed below. It is known that the population standard deviation is o= 8.0. The instructor has recommended that students devote 3 hours per week for the duration of the 12-week semester, for a total of 36 hours. At 10% significance level...

iestion There are n students enrolled in Math 1A in Semester 1, each passes with probability p independently of each of other students. Each student who passes Math 1A will enrol into in Seme that subject with probability p, once again independently of other students. Let X be the total number of students passing Math 1A, and Y be the total number of students passing Math 1B. (a) Determine the probability mass function fy for Y. (b) Are X and...

Suppose that 37% of ONU students have taken an online course. A random sample of 200 ONU students is taken, of which 78 have taken an online course. What is the probability of obtaining a sample proportion this high or higher? There is some thought that the proportion taking online courses is no longer 37%. Based on the random sample, construct a 95% confidence interval for the proportion of ONU students who have taken an online course. ...

Are the grades one receives in a course related to the amount of
time spent studying the subject? To analyze this possibility, a
student took a random sample of 60 students who had enrolled in an
accounting class last semester. She asked each student to report
his or her grade in the course and the total number of hours spent
studying accounting. The data are stored in this Excel file (SEE
