respondents in the treatment group were male, and 20% were female; in the control group

82% were male, and 19% were female (t = -.45, df = 497, p =.622). Within the treatment

group, more respondents (24.4%) fell into the $41,001 to $60,000 income bracket,

followed by 21.4% in the $61,001 to $80,000, and 17.3% in the $100,001 to $150,00

range. In the control group, the greatest percentage of people (20.9%) fell into the

$61,001 to $80,000 income bracket, followed by 20.1% in the $41,001 to $60,000 range

and 17.6% inthe $81,001 to $100,000 category; (t 1.163, df 410, p =0.370).
