Sagot :
Answer:
Approximately 92
Step-by-step explanation:
Using technology, the linear regression model obtained by fitting the data points is:
Y = 0.0914X1 - 0.3741
Where x = test score ; y = average sleep
Slope = 0.0914 ; intercept = - 0.3741
The test score of a student that sleeps 8 hours
y = 8
8 = 0.0914X1 - 0.3741
8 + 0.3741 = 0.0914X1
X = 8.3741 / 0.0914
X = 91.62
