Question

mr. newmans class conducted a survey on the number of chores students completed, and the amount of allowance they earned. bryan thinks the association is negative because they found that as the number of chores decreased, the amount of allowance also decreased. which statement is true? - bryans conclusion is false since both variables of number of chores and amount of allowance are decreasing, which means there is a positive association since the variables are doing the same thing. - bryans conclusion is false since there is no association between the number of chores a student completes and the amount of allowance they receive. - bryans conclusion is true since both variables of number of chores and amount of allowance are decreasing, so there is a negative association. - bryans conclusion is true since the variable of number of chores is increasing and the variable of amount of allowance is decreasing, which means there is a negative association.

Explanation:

To determine the correct statement, we analyze the association between the number of chores and allowance. A positive association occurs when both variables increase or both decrease (they move in the same direction). A negative association is when one variable increases while the other decreases (opposite directions). Bryan claims a negative association, but since both the number of chores and allowance decrease (same direction), it's a positive association. So Bryan's conclusion is false, and the first option explains this correctly. The second option is wrong as there is an association. The third and fourth options misinterpret the association type.

Answer:

A. Bryan's conclusion is false since both variables of number of chores and amount of allowance are decreasing, which means there is a positive association since the variables are doing the same thing.
