The business college computing center wants to determine the proportion of business students who have personal computers (pc's) at home. if the proportion exceeds 30%, then the lab will scale back a proposed enlargement of its facilities. suppose 250 business students were randomly sampled and 75 have pc's at home. find the rejection region for this test using alpha = 0.05

reject h0 if z > 1.645.

reject h0 if z > 1.96 or z < -1.96.

reject h0 if z < -1.645.

reject h0 if z = 1.645.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
