We know that 6% of students will fail a course. If I take a sample of 1200 students who take an online stats course find the probability that more than 100 will fail?

To solve this problem we could do it without Minitab and would be done in the following manner you answer the questions asked where x = number of students who fail

P(x > 100)   x has what type of distribution? ___________________

P(x > 100.5) x has what type of distribution? _____________

P(z > 100-72/8.23) z has what type of distribution? _________________

P(z > 3.40) = 0   Based on this answer if an online course DID had over 100 failures with 1200 students would you recommend that the course be taught online? Explain

Answer #1

Since, the probability of getting more than 100 failures is 0, it is unusual for any test to give such a result. This would imply that the test has a failure score more than 6% and hence it would not be recommended to teach the course online

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1150 on the SAT, with a sample standard deviation of 300. On the basis of these data, can the researcher conclude that the preparation course...

Here's a question from when DM taught this course: We hypothesize that students at DM’s lab have more psychotic episodes than the normal students at SFSU. A sample of 50 students from DM’s lab were randomly sampled and the mean number of psychotic episodes that they had per year was computed to be 27. Given the following information about the number of psychotic episodes per year that the general population at SFSU has, answer the following questions. µ = 25...
