A quаlity-cоntrоl аnаlyst studies whether machine calibratiоn age x, measured in months, predicts precision score y. The analyst expects the relationship may be negative, but you should compute the regression from the data rather than relying on the pattern by sight. Use the following data to compute the simple linear regression equation and then predict y when x = 8.4. x y13 42.253 72.7511 52.757 63.7515 39.755 64.259 51.25 Enter the slope [slope]____, intercept [intercept]____, and predicted ŷ for x = 8.4 [y-hat]____.(round each answer to 2 decimals)
