Question

A researcher builds a statistical model to determine how many credit card charges are fraudulent. Use the model y =1 + 0.02x
to estimate how many credit card charges are fraudulent out of 200 charges.(1 point)
Out of 200 charges, there are
fraudulent charges.

Answer 1

Using the model y = 1 + 0.02x, where x is the number of charges, we can estimate the number of fraudulent charges out of 200 charges as follows:

y = 1 + 0.02(200)
y = 1 + 4
y = 5

Therefore, out of 200 charges, there are 5 fraudulent charges.
