The administration at Plano ISD wants to determine if a students' test scores last spring were related to the amount of time doing homework each week during remote learning. To perform this analysis, data was collected for 40 students who studied between 2 and 10 hours per week during that time period. A computer software package was used to generate the following computer output. Predictor Coef SE Coef T P
Constant 44.540 1.813 24.57 0.000
Study Time 5.5520 0.05501 10.09 0.000

What is the equation for the least squares regression line?

kjgfcvbjkl

step-by-step explanation:

sdfghjkl; vbnm,

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
