Suppose you have a binary randomized controlled experiment designed to measure the causal effect of X on Y. Let the control group be identified by X = 0 and the treatment group by X = 1. The differencesofmeans estimator, denoted by , is an estimator of the causal effect of X on Y because the differencesofmeans estimator estimates: A. the change in the expectation of Y as result of an observation being in the treatment group as opposed to the control group. B. the expectation of Y for observations within the control group. C. the expectation of Y for observations within the treatment group. D. All of the above.

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
