More Taxes; the Rock vs. Reg Guy

The same tax service provider (from the last case - no need to return to it) decided that consumers' intent to purchase might increase if she showed them an ad with the area's old high school sports hero, now local weatherman, Danny "TD" McDonald. To test this, you called back the first group of men and women who saw the ad featuring the Rock (AD_1_Rock) and now showed them an ad with Danny (AD_Reg_Guy).
