1 Slope ERROR:#DIV/0! 13 Slope ERROR:#DIV/0! For every increase of one unit there is a decrease of 1.12 in predicted y
2 Intercept ERROR:#DIV/0! 14 Intercept ERROR:#DIV/0! When there is an absence of x values the predicted y value is 56.0
3 correlation coefficient ERROR:#DIV/0! 15 correlation coefficient ERROR:#DIV/0! There is a negative and weak association between the variables
4 coefficient of variation ERROR:#DIV/0! 16 coefficient of variation ERROR:#DIV/0! 11.2% of the variability present in predicted y can be explained by variability present in
5 17 the model. Another interpretation ends with th phrase: variability present in x.

Only fill in the yellow
equation should look like: y = slope (x) + intercept
