Sample Final for Quantitative Methods/Regression A dataset contains 200 observations of y vs x where: Sx = 1.09 s?, = 36.552 bo = 42.59 bi = -3.835 xbar = 9.937 SST = 3618.648 1 Find rxy, R², Sb1, Se, SSR, SSE, MSE. 2. Construct a 99% Confidence Interval for Beta1. Interpret this interval. 1½:.05%=.0os 3. Is there evidence that Beta1 is less than -2? Use alpha =.05. 4. Construct a 92% Cl for muy, the true population mean of the y values and interpret the Cl.
