Which data step multiplies the values of Quiz1 through Quiz5 by 10?

To determine which data step multiplies the values of Quiz1 through Quiz5 by 10, it's important to analyze what each of the steps is doing specifically with regard to the variables involved.

If step2 contains the necessary code that explicitly multiplies each Quiz variable (Quiz1, Quiz2, Quiz3, Quiz4, Quiz5) by 10, then this would validate the response. In a standard SAS data step, you might see statements that look like this:

data output;

set input;

Quiz1 = Quiz1 * 10;

Quiz2 = Quiz2 * 10;

Quiz3 = Quiz3 * 10;

Quiz4 = Quiz4 * 10;

Quiz5 = Quiz5 * 10;

run;

This code shows a clear operation where the values of the Quiz variables are directly manipulated by multiplying by 10.

If step1, on the other hand, does not perform this operation or does not involve those specific variables, it would not contribute to the desired result of multiplying Quiz1 through Quiz5 by 10.

Thus, the reason step2 is the correct answer is that it directly addresses the requirement of multiplying the specified Quiz variables by 10,
