In a particular faculty 60% of students are men and 40% are women. In a random sample of 50 students what is the probability that more than half are women?Let the random variable X = number of women in the sample. Assume X has the binomial distribution with n = 50 and p = 0.4.a. What is the expected value and variance of the random variable X?b. Calculate the exact binomial probability. c. Are the conditions that permit you to use a normal approximation to the binomial satisfied? Explaind. Recalculate the probability in part b using a normal approximation without the continuity correction. e. Recalculate the probability in part b using a normal approximation with the continuity correction.
