QUESTION 14 QUESTION 14 Find the indicated binomial probability. Round to five decimal places when necessary. A multiple choice test has 30 questions, and each has four possible answers, of which one is correct. If a student guesses on every question, find the probability of getting exactly 12 correct.
A multiple-choice test consists of 23 questions with possible answers of a, b, c, d. Estimate the probability that with random guessing, the number of correct answers is at least 10. USE NORMAL APPROXIMATION!
Part II. Applying the Binomial distribution. 1. If x is binomial with n-50, pro.9, use Excel to compute P(x s 40)- 2. A student takes a multiple choice test with 100 questions. Each question has 4 choices and only one choice is correct. The student guesses the correct answer for each question. If xenumber of correct guesses, then x is a binomial random variable. Fill in the following values: a) n b) To pass the test, the student must get...
