Ben and​ Mildred's Stables used two different independent 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 $1,004.95 $217.91 4.61 Independent variable $22.78 $3.23 7.09 2 = 0.56 Number of horses: Variable Coefficient Standard Error t-Value Constant $5,241.40 $1,180.37 4.44 Independent variable $951.60 $271.85 5.25
