An operations manager was interested in determining if there is a relationship between the amount of training received by production line workers and the time it takes for them
To trouble shoot a process problem.A sample of recently trained line workers was
Selected.The number of hours of training time received and the time it took (in minutes)
For them to trouble shoot their last process problem were captured. Based on the scatterplot of the data shown, we can say that
A)The slope of the regression line fit to these data will be positive.
B)The slope of the regression line fit to these data will be negative.
C)The linearity assumption is not satisfied.
D)The intercept of the regression line fit to these data will be negative.
E)The equal variance assumption is not satisfied.
