Dаtа fоr оutcоme Y аnd single predictor X was collected on 25 observations. We're given the following R output from a simple linear regression model modeling outcome Y and predictor X: > reg = lm(y ~ x) > summary(reg) Coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) -0.8542 1.5503 -0.551 0.586939 x 0.9121 0.2190 4.165 0.000373 *** --- Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 Residual standard error: 3.058 on 23 degrees of freedom We also know the range of X is [0,11]. Use the regression equation to predict Y when X is each of the following:
