Question
Consider the following four studies below and then match them accordingly to their
sampling type.
Study 1: Henrietta manages a movie theater that recently completed a remodel. She would like to learn what her customers think about it. So she decides to give every 20th person that enters the theater a survey that asks them their opinion of the remodel.
Study 2: Suppose a research team wants to determine the average GPA of college
students in the U.S. They choose to have their sample represent the target population in terms of major and know from a different study that 12% majer in English, 28% major in science, 15% major in computer science, 21% major in engineering, 5% major in
mathematics, 10% major in the arts, and the remaining 9% have a different major. In their sampling procedure they are careful to make sure that their sample has these exact
percentages, in terms of major, by performing a simple random sample within each of
these subgroups.
Study 3: A raffle takes place where attendants are each handed a single ticket number that is placed into a bag and certain prizes are given to the people whose ticket numbers are drawn.
Study 4: A raffle takes place where attendants are able to buy as many tickets as they
would like--each with a number-- that is placed into a bag and certain prizes are given to the people whose ticket numbers are drawn

The appraiser wants to test the popular belief that the average sales price is $37.80 per square foot for such homes. Suppose that a random sample of six sales were selected. The sampled sales prices per square foot are $35.00, $38.10, $37.20, $29.80, $30.30, and $35.40. Assuming a normal distribution is a good model for sales, test the claim that the mean sales price per square foot differs from $37.80 at the 1% significance level.arrow_forward(6) A student surveys some students on campus in the evening and finds that 16 out of 20 of the students she interviewed are part time students.
