Eighty percent of the students applying to a university are accepted. Using the binomial probability tables or Excel, what is the probability that among the next 20 applicants: 1. Exactly 10 will be accepted? Why is this number so low? (#4 might help) 2. At least 14 will be accepted? (14 or more will be accepted) 3. Exactly 5 will be rejected? 4. Determine the expected number of acceptances. 5. Compute the standard deviation. I do not know how to...
70% of the students applying to a university are accepted. Assume the requirements for a binomial experiment are satisfied for 10 applicants. a. What is the probability that among the next 10 applicants 8 or more will be accepted. b. What is the probability that among the next 10 applicants 4 or more will be accepted? (Use the binomial table for this problem) c. What is the expected number of the next 10 applicants that will be accepted?
Suppose the event of a student’s application to a university being accepted follows the binomial probability. The successful rate is 80%. Please finish the following tasks? (1) Determine the expected number of acceptances for the next nine applicants and the standard deviation. (2) What is the probability that among the next 10 applicants exactly 6 will be accepted?
