The collection of emerald-cut diamonds contains replications, several diamonds at each weight. Had we fit the linear equation using average prices at each weight rather than individual diamonds, how would the fitted equation and summary measures (rsquared2 and se) change? The slope would increase significantly and the intercept would be approximately the same. The value of s Subscript ese would increase significantly and rsquared2 would decrease significantly. Solution The slope would increase significantly the intercept would be approximately the same. The value of s e would increase significantly rsquared2 decrease significantly..
