4. Cluster sampling: The registrar of a university with a population of N=4000 full-time students is asked by the president to conduct a survey to measure satisfaction with the quality of life on campus. The registrar intends to take a probability sample of n=200 students and project the results from the sample to the entire population. Suppose that each of the n=4000 registered full-time students lived in one of the 10 campus dormitories. Each dormitory can accommodate 400 students. It...

Probability Sampling You are interested in finding out the proportion of the population of UTSA students who are enrolled in majors within the College of Liberal and Fine Arts (COLFA). The UTSA registrar provides you a list of all registered students for Fall 2017. From this list, you select a random sample of 300 students and administer surveys to all of them. When you analyze your surveys you find that 22% of your sample identify as COLFA majors. You later...

Suppose that a certain college class contains 47 students of these, 28 are sophomores, 27 are business majors, and 8 are neither. A student is selected at random from the class. (a) What is the probability that the student is both a sophomore and a business major? (b) Given that the student selected is a business major, what is the probability that he is also a sophomore? Write your responses as fractions. (If necessary, consult a list of formulas.)

Suppose a survey of 1000 students is obtained from a college whose population is 10,000 students. The sample was obtained by selecting at random from the population without replacement, meaning that no student could be selected twice. Although it is true that if the probability of selecting any one particular student is equal to the probability of selecting any other particular student then the sample is random, in this case, sampling was done without the probability of selecting the first...
