Refer to the data on \"Tensile Strength of Cement\". Hand et al. describe the data set as follows: \"The tensile strength of cement depends on (among other things) the length of time for which the cement is dried or 'cured'. In an experiment, different batches of cement were tested for tensile strength after different curing times. The relationship between curing time and strength is nonlinear. Hald regresses log tensile strength on the reciprocal of curing time.\" (a) (b) (C) ((1) Obtain a scatterplot of tensile strength on curing time. Obtain another scatterplot of logw(tensile strength) on lf(curing time). Fit a pseudolinear model to the data as plotted in (b) by letting Y = logm(tensile strength) and X = lf(curing time).] State the tted model equation, and superimpose the straight line on the scatterplot in (b). You will hand this graph in; don't forget to label the axes properly and put a title on the graph. Now use the equation from (c) to t a curve on the scatterplot in (a). You will hand this graph in. What is the equation of the curve yOu t? [Hints on how to get R to draw the curve will come in class] A B C Curing Tim TensileStrength 2 1 13 3 1 13.3 4 1 11.8 5 2 21.9 6 2 24.5 2 24.7 8 29.8 28 10 W 24.1 11 3 24.2 12 26.2 13 7 32.4 14 7 30.4 15 7 34.5 16 7 33.1 17 7 35.7 18 28 41.8 19 28 42.6 20 28 40.3 21 28 35.7 22 28 37.3 23
