State dmv records indicate that of all vehicles undergoing emissions testing during the previous year, 70% passed on the first try. a random sample of 200 cars tested in a particular county during the current year yields 160 that passed on the initial test. does this suggest that the population proportion for this county during the current year differs from the previous statewide proportion? conduct hypothesis test using α =0.05

87%

step-by-step explanation:

apex answer

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

im not sure what the answer is

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
