- A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 90.2% for the medical students admitted through special programs. Be sure to enter at least 4 digits of accuracy for this problem! If 9 of the students from the special programs are randomly selected, find the probability that at most 6 of them graduated.P(at most 6) = At least 4 digits! Would it be unusual to randomly select 9 students from the special programs and get at most 6 that graduate? no, it is not unusual yes, it is unusual Would it be unusual to randomly select 9 students from the special programs and get only 6 that graduate? no, it is not unusual yes, it is unusualPlzA company did a study of available vacation time for their staff employees over the past years. They determined the probability a staff employee selected at random has 2 weeks’ vacation was 45%, 1 week vacation 10%, 3 weeks’ vacation 20%, and more than 3 weeks’ vacation was 25%. The company randomly selects 20 employees. What is the probability that out of the 20 selected, at least 2 workers have 1 week vacation time?

It found that 40% of users who had ≤ 100 injections per month (light users) and 55% of users who had > 100 injections per month (heavy users) were HIV positive. A. Suppose we have a group of 10 light users and 10 heavy users. What is the probability that exactly 3 of the 20 users are HIV positive? B. What is the probability that at least 4 of the 20 users are HIV positive? Please show me the calculations by hand and not excel, I am trying to learn how to plug in these formulas myself and to solve without computer assistance.

- In a study of 213,270 cell phone users, it was found that 77 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000397 probability of a person developing cancer of the brain or nervous system. We therefore expect about 85 cases of such cancer in a group of 213,270 people. Estimate the probability of 77 or fewer cases of such cancer in a group of 213,270 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(x ≤ 77) = (Round to four decimal places as needed.)The Ministry of Agriculture in its fight against the army worm infection of maize farms in the country has approved three brands of chemicals A, B and C to be used by farmers as follows: Farmers are to combine exactly two of the chemicals to spray their farms or they should use none of them. The proportions of farmers who opted for chemicals A, B and C are respectively given by 1 , 1 and 7 . A farmer is randomly 53 15 selected from the group of farmers. What is the probability that the farmer chose none of the chemicals?
