Here is a simple probability model for multiple-choice tests. Suppose that each student has probability p of correctly answering a question chosen at random from a universe of possible questions. (A strong student has a higher p than a weak student.) The correctness of answers to different questions are independent. Jodi is a good student for whom p = 0.8. Use 4 decimal places. (a) Use the normal approximation to find the probability that Jodi scores 75% or lower on...

Here is a simple model for multiple-choice tests. Suppose that each student has a probability of p of correctly answering a question chosen at random from a universe of possible questions. (a strong student has a higher p than a weak student.) The correctness of answers to different questions are independent. Jodi is a good student for whom p= 0.76. (c) How many questions must the test contain in order to reduce the standard deviation of Jodi's proportion of correct...

Zoe is taking a test with 100 questions. There are 30 True/False questions and 70 multiply-choices questions (4 choices per question). Suppose that she blindly guesses all the questions and the results of the different questions are independent. Approximate the probability that (a) she answers at least 40 questions correctly. (b) she gets more correct answers on True/False questions than she does on multiplychoices questions.
