Answer:

Step-by-step explanation:

f(x) = -1/2x^4

Because x^4 is being multiplied n=by a negative number, the parabola will face down. That means it is between a and b. To figure out which graph it is, I look at points I could compare.

In graph A, when x=1, y < 1. In graph B, when x=1, y>1.

If i plug x= 1 into f(x), I get:

f(1) = -1/2(1)^4

f(1)=-1/2(1)

f(1)=-1/2

Because f(1) < 1, it is graph A.

Answer:

Hence, the data provides convincing evidence that a linear relationship exists between hours of sleep observed and academic performance as measured by GPA.

Step-by-step explanation:

Given the data:

Sleep (hrs) 9 8.5 9 7 7.56 7 5.5 6 8.5 6.5 8

GPA 3.8 3.3 3.5 3.6 3.4 3.3 3.2 3.2 3.2 3.4 3.6 3.1 3.4 3.7

The scatter plot shows a positive linear trend. With the correlation Coefficient depicting a R value of 0.56. The residual plot also depicts a a randomly scattered values of the residual values. Similarly, a plot of the normal values of residuals
