The amount of rain for three months (June, July, and August) was recorded for each of three cities. Using the data in the following table, create a SAS data set (RAIN) containing the variables CITY, RAIN_JUNE, RAIN_JULY, and RAIN_AUGUST. Create four additional variables in this data set: AVERAGE, PERCENT_JUNE, PERCENT_JULY, and PERCEN1,--AUGUST. AVERAGE is the average of the rain for the three months. Each of the PERCENT variables is computed as rainfall for the month as a percent of the AVERAGE. For example, PERCENT_JUNE would be 100 X 23/26. Provide a listing of the data set in alphabetical order of CITY, with CITY as the ID variable. Then compute the mean, standard deviation, and the 95% confidence interval (CT) for the three RAIN variables (with all statistics printed with two decimal places). Here are the data:
