C)will conclude that there is a significant relationship between amount of training 
D)both A and C

Quizplus · Accepted Answer

The p-value for the coefficient of the amount of training received is less than 0.05, which means we can reject the null hypothesis and conclude that there is a significant relationship between the amount of training received and the time it takes to trouble shoot a process problem. Therefore, choice A and C are both correct.
