In a 3 races, 2 genders and 5 in each treatment group for two-way ANOVA, the degree of freedom for source of variation due to interaction, error and total respective are
The Pearson's correlation coefficient between following observation
| X: | 1 | 2 | 3 | 4 |
| Y: | 3 | 4 | 2 | 1 |
is -0.8. If each observation of X is halved and of Y is doubled, then Pearson's correlation coefficient equals to
