Answer:
Step-by-step explanation:
A) There is a positive correlation between the hours of homework and the test scores. Generally the more hours spent on homework the the higher score on the test
B) We need to predict for 3 hours of homework put x=3 in above function as x represents hours of homework we get:
y=8(3)+40
y=24+40
y=64
Hence test score will be 64 for 3 hour of homework.
C) 40 would be the test score if no time was spent doing homework
