You are interested in the US presidential elections and decide to analyze whether or not the presidential candidate for a particular party did better if his party controlled the House. Accordingly, you collected data for all the past elections and generated the accompanying table: (table attached in the photo) (a) Should you interpret your data as the "population", or a "sample" from which you want to infer the behavior of a larger population? (b) Compute E(Y). (c) Conditional on a Democratic president, what is the probability that the Republications had control of the House during this term? (d) Compute Var(Y l X=0).
