1. In a large university, 10% of the students are marketing majors. A random sample of 100 students is selected, and the proportion of those who are business majors is calculated. Assume the population is infinite. Compute the standard error of the proportion in the sample.

2. Compute the expected value of the sample proportion.

3. What is the probability that the sample contains more than 16 marketing majors?

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...
