Suppose that Mary, Gary, and Larry have been asked to randomly sample 100 patients' visit records
from a file of 2000 patient records and record the amount of time the attending physician spent with
each patient. Gary suggests the time of year during which the patient was seen may be a confounding
variable and strongly advises dividing the year into quarters (Jan - Mar, Apr-Jun, Jul-Sep, Oct-
Dec) and randomly selecting 25 patient records from each quarter. Which of the following best
describes Gary's sampling plan?
(A) A simple random sample
(B) A systematic random sample
(C) A stratified random sample
(D) A cluster sample
(E) A convenience sample

) According to the PayScale data from 2021, the average starting salaries by
college major for bachelor's degree are as follows: $70,600 for mechanical engineering,
$56,700 for economics, $43,500 for chemistry, and $47,000 for philosophy. In order to
estimate the true difference in the average starting salaries by college major in 2022, 60
graduates with these four majors from the class of 2022 were contacted and questioned
about their starting salaries. Propose a regression model with dummy variables that could
be used to investigate if starting salaries are different by college major and interpret all
the coefficients in the model.

- The managers of a brokerage firm are interested in finding out if the number of new clients a broker brings into the firm affects the sales generated by the broker. For the last year, the managers sampled 16 brokers and determined the number of new clients they enrolled during that year and their sales amounts in millions of dollars for that year. This data is presented in the table that follows. In your answers, sales should be left as a decimal as in the data table. It is not necessary to multiply by one million dollars. Perform a simple linear regression analysis of this data and answer the following questions. Suggestion: Read all of the questions before doing any analysis.
