Answer 1

Answer:

Part A

5yr old boy.

Y=-(1/8)x+113/8 x=5

Y=-5/8+113/8=(113-5)/8=108/8

Y=13.5 hrs

Yes the estimated value of sleep by this function is reasonable as it is close to childhood more sleep is likely.

Part B

20yr old boy.

Y=-(1/8)x+113/8 x=20

Y=-20/8+113/8=(113-20)/8=93/8

Y=11.63 hrs

No the estimated value of sleep by this function is not reasonable as the normal sleep of 7-8 hrs is enough for adults.
