4. The Internet site www.golfcourse.com listed 14,938 golf courses by state. It gave a variety of information about each course, including greens fees, course rating, par for the course, and facilities. Data from an SRS of 120 of the golf courses is in file "golfnsrs.csv". A simple random sample of 120 golf courses, taken from the population. Variable Name Description random number used to select golf course for sample state name RN state wkday9 holesn greens fee for 9 holes during week 1=18 holes and 0=not 18 holes sampwt Sampling weight 4a) The data set already contains the sampling weight, "sampwt". Show how we can calculate the sampling weight. • Using the same data set ("golfnsrs.csv") and using SAS SURVEYMEANS procedure, please answer to the questions 4b), 4c), and 4d) below. 4b) Display the data in a histogram for the weekday greens fees for nine holes of golf (using "wkday9"). How would you describe the shape of the data? 4c) Find the average weekday greens fee to play nine holes of golf (using "wkday9"), and give the standard error (SE) for your estimate. 4d) Estimate the proportion of golf courses that have 18 holes (using "holesn"), and give a 95% Cl for the population proportion. 4.
