Determine whether the underlined value is a parameter or a statistic. a study of 6076 adults in public rest rooms found that 23% did not wash their hands before exiting. is the value a parameter or a statistic?

a. the value is a parameter because the 6,076 adults in public rest rooms are a sample
b. the value is a parameter because the 6,076 adults in public rest rooms are a population.
c. the value is a statistic because the 6076 adults in public restrooms are a sample
d. the value is a statistic because the 6,076 adults in public rest rooms are a population

C

Step-by-step explaination:

A statistic is a data obtained by sampling a population

A sample is a part of a population studied for the purpose of testing of an hypothesis

6076 is a statistical value because it represents a part (sample) of the whole population

step-by-step explanation:

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
