10. Twenty percent of the students in Quant 2600 are female. Use the normal approximation of the binomial probabilities to answer the following questions. What is the probability that in a random sample of 100 employees a. What is expected value (mean) of the number of females in the class? You will need this for parts c and d. b. What is the standard deviation for the number of females in the class? Use 2 decimal places. You will need this for parts c and d. (2 decimal places) c. What is the probability of 24 or more are females? Use 4 decimal places d. What is the probability of 15 or fewer
