-A researcher predicts that people with higher levels of racism (measured on a scale of 1 to 8, with higher numbers meaning more racism) will offer a smaller starting salary to a potential employee who is a racial minority. Given r = –.62, MX= 5.26, SX= 2.33, MY = 350.23, and SY= 25.03, which of these best characterizes the relationship between racism and salary offers?

A practically significant predictive relationship does not exist between these variables

A one-point increase in racism is associated with a 6.66-dollar decrease in starting salary offers.

A one-point increase in racism is associated with a 2.33-dollar decrease in starting salary offers

A one-point increase in racism is associated with a 0.06-dollar decrease in starting salary offers.
