A recent survey found that 63% of college students attend more than one institution during their college career. Suppose a sample of 9 students is chosen. Assuming that each student's college attendance pattern is independent of the others, answer the following questions. a. What is the probability that at least 4 of the 9 students attend more than one institution? Enter your answer in decimal form rounded to four decimal places if rounding is necessary. b. What is the probability that between 2 and 5 students attend more than one institution (including 2 and 5). Enter your answer in decimal form rounded to four decimal places if rounding is necessary. c. What is the probability that exactly 6 of the 9 students attend more than one institution? Enter your answer in decimal form rounded to four decimal places if rounding is necessary. d. What is the probability that at most 5 of the 9 students attend more than one institution? Enter your answer in decimal form rounded to four decimal places if rounding is necessary. e. What is the probability that exactly 6 of the 9 students do NOT attend more than one institution. Enter your answer in decimal form rounded to four decimal places if rounding is necessary. f. In the sample of 9 students, how many are expected to attend more than one institution? Round your answer to the nearest whole number if rounding is necessary. g. In the sample of 9 students, what is the standard deviation of the number of students who will attend more than one institution? Round your answer to four decimal places if rounding is necessary.
