Ilia_Sergeevich [38]

Using sampling concepts, it is found that the correct option is given by:

B. The Golf Federation's conclusion was not valid because the sample was biased since the male customers all lived in California.

<h3>What is sampling?</h3>

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, the objective is to make an estimate about the most popular brand of golf ball from men all over the United States, however, only customers from California were chosen, hence the sample is not representative and option B is correct.

I need help with these two questions can some explain it to me how to do these two question
GrogVix [38]

the numbers inside the () are first number is x second number is y so it is (x,y)

so for y<x the second number needs to be smaller than the first number

 so right away (3,3) is not the answer

 and then y also has to be greater then 2x-3

 so replace x with the fist numbers and see what you get.

(2x2)-3 = 4-3 = -1 since -1 is not greater than -1 the second answer (2,-1) is not right

 3rd one (-1,-2) 2(-1)-3 = -2-3=-5

so -2 is greater than -5 and -2 is less than -1 so the 3rd one is the answer
