QUESTION 8 Assume the probability that a random member of the UIC community has recieved a COVID vaccine is 20%. Also assume there are 300 people on campus on a given day. A public health official would like to know the probability that less than 50 of the 300 total have received a vaccine. This probability calculation requires a sum of many binomial distribution terms. Instead, the public health official will use a normal approximation. What mean parameter value should be used for the normal distribution? QUESTION 9 Assume the probability that a random member of the UIC community has recieved a COVID vaccine is 20%. Also assume there are 300 people on campus on a given day. A public health official would like to know the probability that less than 50 of the 300 total have received a vaccine. This probability calculation requires a sum of many binomial distribution terms. Instead, the public health official will use a normal approximation. Let X = the number of people out of the 300 total that have received the vaccine. What x-value should be used when peforming the normal approximation probability calculaiton, i.e. P (X
