On the first day of class, students took a survey and were all asked to guess the population of Santa Clara county but the students were given one of two different forms (either a control or treatment form.) The variable BEST_GUESS contains the population estimates from this survey, and the variable TREATMENT is an indicator of whether or not a respondent was in the control or treatment groups. Do these results indicate respondents in the treatment group provided lower population estimates on average? Are the results statistically significant?
