Answer 2

haha whats up with all the ghosts

Answer 3

The sign of the coefficient indicates the slope of the linear fit. If the sign of the correlation coefficient is positive, then the slope is positive. If the sign of the correlation coefficient is negative, then the slope is negative.

Answer 4

Take a look at the attached chart of scatter plots and associated coefficients of correlation.

Then, look at your scatter plot and see if you can come up with an answer.

Post it, okay, so that someone can check. @CrazyCountryGirl
