Suppose again we are interested in modelling the relationship between a person's writing handrspan and their height. Further suppose that a new group of students have been asked in a survey what their writing hand span and height are, in cm. For this analysis, we have that: . "he response variable, y, is height . 'he explanatory variable. cc. is writing handspan. Based on the responses received, the results of the analysis are provided below: Cal?) lm( ormula = df$Height ~ df$Wr.Hnd, data = df) Residuals: Min 10 Median 30 Max 15.4448 4.1266 0.1068 4.4483 21.08?9 Coefficients: Estimate Std.
