In a large university, statistics show that 75% of students live
in dormitories. Thus, for any student chosen at random, the
university administration estimates a probability of 0.75 that the
student will live in dormitories. A random sample of 5 students is
selected. Answer the following questions.
1.What is the probability that the sample contains exactly 3
students who live in the dormitories?
2.What is the probability that fewer than 2 students live in the
dormitories?
3.What is the expected...

Researchers equipped random samples of 46 male and 58 female
students from a large university with a small device that secretly
records sound for a random 30 seconds during each 12.5-minute
period over two days. Then they counted the number of words spoken
by each subject during each recording period and, from this,
estimated how many words per day each subject speaks. The female
estimates had a mean of 16,177 words per day with a standard
deviation of 7520 words...
