Which of the following estimated parameters change as result? (Check all that apply) The eatimated intercept and slope. The R of the regression. The standard error of the regression (SER). YD. The standard errors of the estimated coefficients. Using the 390 observations, what results will be produced by his regression program? Ý= 32.68 + 67.65X, SER =.R = 0.84 (Round your responses to two docimal places)
