Based on the LSD you just found conduct a test of the hypothesis that the mean savings for the populations of people ages 60-69 and those aged 70 are equal. Use a .05 level of significance for your test. True or false: you reject the null hypothesis that the mean retirements savings are the same for these two poulations

just for that im not answering

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
