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 a = .05

- reject h is z is greater than 1.645

reject h is z= 1.645

reject h if z is less than -1.645

reject h if z is greater than 1.96 or z is less than -1.96

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

the correct option is b
