question 78

Essay

The bigger the stop sign, the more expensive it is. Here is a graph of the height of a sign in inches versus its cost in dollars. The bigger the stop sign, the more expensive it is. Here is a graph of the height of a sign in inches versus its cost in dollars.  To achieve linearity, the data was transformed using a square root function of cost. Here are the results and a residual plot.Dependent Variable: sqrt(cost)   \mathrm{R}   (correlation coefficient)   =0.98946627     \mathrm{R}-\mathrm{sq}=0.97904349   s: 0.2141   \begin{array}{lrr} \text { Parameter } & \text { coeff } & \text { se } \\ \text { Intercept } & 1.1857 & 0.4346 \\ \text { height } & 0.1792 & 0.0151 \end{array}    -Use your equation to predict the cost of a 48  stop sign.
