The 2016 ANES Pilot Survey of a nationally representative sample of American adults asked respondents to rate political groups on a 0 to 100 degree "feeling thermometer" scale, where 0 indicates extreme coldness (or dislike), 100 indicates feelings of great warmth (or affection), and 50 indicates respondents feel neither warmly nor coldly (neutrally). ftsanders measures feeling thermometer scores toward Senator Bernie Sanders. You want to see if there is a statistically significant gender gap in average feeling thermometer scores toward Bernie Sanders. Assume that Males are Group 1 and Females are Group 2. Let's examine this problem in a hypothesis testing context (assume a two-sided alternative).
