. In preparation for your Biology midterm, you decide to look up past exams to see what kinds of questions were on it. Let B be the event “a question about bacteria shows up on the exam”, and let M be the event “a question about mitosis shows up on the exam”. From past exams, you know that P(B) = 0.3, P(M) = 0.8, and P(M and B) = 0.4. What is the probability of either/or of these types of...

Whereas grading students’ homework is an important aspect of a professor’s job, reviewing homework solutions is an important ingredient in the learning process for a student. Research indicates that the longer it takes a professor to grade a homework the less likely that a student will review the homework solutions, when made available. In the past, in Professor Johnson PHYS 500 class, nonadherence on part of a few students to a prescribed HW submission format has often delayed the turnaround...

A professor is interested in determining how difficult his exams are. He decides to examine past grades on his first exam, the content of which has remained more or less the same over the last several years. In a random sample of 15 exam scores, the sample mean was 75 with a sample standard deviation of 5. The upper bound of a 95% confidence interval for the true mean, to two decimal places, would therefore, be which of the following?...
