data point and compute the residual. Enter the exact answers. Predicted value= lbs Residual= lbs (b) Interpret the slope in context. Given a 1 pound increase in Weight, expected change in Training is 11.8 hours. Given a 1 hour increase in Training, expected change in Weight is 11.8. Given an 11.8 hours increase in Training, expected change in Weight is 1 pound.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
