質問 1:Scenario:
Open the existing program, program48.sasfrom folder cert\errors. At any time, you may save your corrected program asprogram48incert\programs. This program is intended to:
* Create 3 groups for C var: A-G is Group=1; H-N is Group=2; O-Z is Group=3.
* All variations of the variable should be in the same group, i.e. "A" and "a" should be in Group=1.
* Calculate the average of X and Y by Group. There are multiple errors in the program. These may be syntax errors, logic errors, or problems with the program structure. Logic errors might not produce messages in the log, but will cause the program to produce results different than intended. Correct the errors, run the program, and then use the results to answer the next 2 questions. What is the average (mean) of X for Group=2? Enter your answer to the nearest whole number. Enter your numeric answer in the space below:
