The cost of repairing cars involved in collisions is one reason insurance premiums are so high. In an experiment, 10 cars were driven into a wall. The speed was varied between 2 and 20mph. The cost of repair was estimated and was listed in the table below: Speed Cost 24 358 CO 519 699 816 905 TLER 1521 1888 2201 Draw an appropriate graph to analyse the relationship between the two variables. How strong is the relationship between the two variables? Calculate the mean and standard deviation of cost. What is the median of cost? Compute the coefficient of determination and interpret the result. Determine the correlation coefficient
