indicated probability by using the normal distribution as an approximation to the binomial distribution. 12) A multiple choice test consists of 60 questions. Each question has 4 possible answers of which one is correct. If Estimate the all answers are random guesses, estimate the probability of getting at least 20% correct.
(1 point) Use normal approximation to estimate the probability of getting at most 45 girls in 100 births. Assume that boys and girls are equally likely. (1 point) A coin is tossed 12 times. b) What is the probability of getting exactly 2 heads? (1 point) An airline company is considering a new policy of booking as many as 336 persons on an airplane that can seat only 300. (Past studies have revealed that only 81% of the booked passengers...
A binomial distribution has p=o.22 and n=98. Use the normal approximation to the binomial distribution to answer parts a through d. a. what are the mean and standard deviation for this distribution? b. what us the probability of exactly 16 successes? c. what is the probability of 14 to 25 successes? d. what is the probability of 12 to 20 successes?
Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. The mean number of births per minute in a country in a recent year was about seven. Find the probability that the number of births in any given minute is (a) exactly five, (b) at least five, and (c) more than five. (a) P(exactly five)...

compute p(x) using the binomial probability formula. then determine whether the normal distribution can be used to estimate this probability. if so, p(x) using the normal distribution and compare the result with the exact probability. n=78, p= 0.83, and x=60 for n= 78, p= 0.83, and x=60, find P(x) using the binomial probability distribution. P(x) _. (round to four decimal places as needed.) can the normal distribution be used to approximate this probability? A. no, the normal distribution cannot be...
