A multiple-choice test consists of 115 questions with possible answers ofa, b, c, d, e. Let us say that you randomly guessed on each question (each questionhas one correct answer) and we want to look at the number of correct responses.np =n(1 − p) =Both these values are bigger thanCan we use the normal approximation to the binomial distribution (type YES or NO)?What is the probability of the number of correct responses being:a) at least 30 ?b) less than 30 ?c) is between 27 and 30 (inclusive) ?

Given,Sample size, n = 115Since, each question has one correct answer out of 5 possible answer. So…

You need to compute the probability of 5 or fewer successes for a binomial experiment with 10 trials. The probability of success on a single trial is 0.54. Since this probability of success is not in the table, you decide to use the normal approximation to the binomial. Is this an appropriate strategy? Explain. O No, np 5. O No, np > 5.

n studies for a medication, 15 percent of patients gained weight as a side effect. Suppose 541 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that a) exactly 82 patients will gain weight as a side effect. (b) no more than 82 patients will gain weight as a side effect. (c) at least 92 patients will gain weight as a side effect. What does this result suggest?
