Question

DOES ANYONE KNOW HOW TO DO THIS PROBLEM???? I AM NOT SURE HOW TO SOLVE THIS PROBLEM!!!!!!!!!!!!!!!!!

Answer 1

Filled table below

Explanation:

There are three columns to fill out according to the requirements of the question:

The observed time will be taken from the given table (or scattered points in the graph)

The predicted time will be computed from the equation of the best fit line

The residual will be the difference between both

For x=4.0, the time spent exercising is 4.5 hours

If we use the line, we have

`y=-0.4x+7.02= -0.4(4.0)+7.02=5.42`

The residual is 5.42-4.5=0.92

For x=5.0, the time spent exercising is 6.5 hours

If we predict with the line, we have

`y=-0.4x+7.02= -0.4(5.0)+7.02=5.02`

The residual is 5.02-6.5=-1.48

The values will be shown in the table below
