A scientist study the relation of x=salinity level and y=nitrate level. He fitted a simple linear

regression of y on x and got the following ANOVA table.

Analysis of Variance Table

Source                         df                    SS                    MS                  F                      p-value

X                                 1                      64.496             64.496 0.0000

Residual                      6                      6.113   

  1. MSE and F-statistic are missing in the table, please fill in.
  2. What is his sample size n?
  3. What is y’s total variation?
  4. what is the sample standard deviation sy?
  5. If we know x and y are negatively correlated, what is the sample correlation coefficient

between x and y?

  1. If we know the fitted regression line is y = 326.976    8.404x, what is x’s sample standard deviation sx?
