Answer:
a. There is a causation relationship and positive trend between number of hours on homework and higher test scores.
b. 76
Explanation:
a. Since the dots all follow a linear progression and increase closely together this is a positive trend and likely a causation relationship.
b. y=7x+41 can predict a test score. x is the number of hours, so if 5 if the number of hours then y=7(5)+41 = 35+41=76
