A student says that the larger the absolute value of r is, the greater the probability that a change in the explanatory variable will cause a change in the response variable. What would you tell the student?

Step-by-step explanation:

The student has a valid point but here's what I would tell him or her:

The larger the absolute value of r, the greater the probability that an increase in the value of the explanatory variable will cause an increase in the value of the response variable.

"r" here represents the correlation coefficient (Pearson's correlation coefficient) which shows the direction and strength of relationship between two variables.

The explanatory variable is the independent variable. It is the variable that places an effect on the other.

The response variable is the dependent variable. It is the variable which is observed for an effect.

When r is positive, it means that both variables move (increase or decrease) in the same direction. When the absolute value of r is large, it shows a great magnitude of change.

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
