There are 435 representatives in the 113th session of the U.S. House of Representatives. On the website www.house.gov, you can find an alphabetized list of the 435 congresspersons. In 2013, the first representative listed is Robert Aderholt, a Republican from Alabama, and the last representative listed is Todd Young, a Republican from Indiana. Suppose that the alphabetized list is indexed 1 through 435.

a. Use systematic random sampling to obtain a sample of 15 of the 435 representatives.
b. Suppose that, in Step 2 of Procedure 1.1, the random number chosen is 12 (i.e., k = 12). Determine the sample.
