A poll surveyed 1801 internet users and found that 854 of them had posted a photo or video online. Assume that you want to test the claim that less than half of internet users have posted photos or videos online? Use LaTeX: \alpha=0.01α = 0.01 level of significance. Find the critical number (z or t) that is corresponding to the given significance level. Round to 4 decimal places.

step-by-step explanation:

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
