c. Analysis of cost behaviour (2 marks): Pam's Stables used two different predictor variables (trainer hours and number of horses) in two different equations to evaluate the cost of training horses. The most recent results of the two regressions are as follows: Trainer's hours: Variable Coefficient Standard Error t-Value Constant 913.32 2.093 4.44 Predictor Variable 20.90 2.844 3.50 r2 = 0.56 Number of horses: Variable Coefficient Standard Error t-Value Constant 4764.50 0.812 4.61 Predictor Variable 864.98 0.294 3.40 2 = 0.83 What is the estimated total cost for the coming year if 13,000 trainer hours are incurred and the stable has 400 horses to be trained, based on the best cost driver?
