Let Y denote a firm’s profit margin as a decimal/proportion, where typical values in the industry you’re studying are from Y=0.00 to Y=0.15; for example, Y=0.08 means 8% profit margin. Let X denote the firm’s share of employees who have an economics degree as a decimal/proportion; for example, X=0.15 means 15%. You run OLS, computing a slope estimate of 0.0002 and 95% CI of [-2.0202, 2.0202]. Among the following, the most reasonable interpretation is:

Your company wants to learn the effect on worker productivity of blocking Facebook on work computers. They form pairs of similar workers and randomly pick 1 of the 2 workers in the pair to block from Facebook. Imagine they can measure Y, the productivity difference in hours per day; i.e., the blocked worker’s productive work time minus the non-blocked worker’s productive work time. From their sample, their estimate of E(Y) is 0.98, and the CI is [-1.02, 2.98].  Among the following, the most reasonable interpretation is:
