State whether the following statements are True or False. (5 marks, 1 Mark Each)

1- If x and y have a strong positive linear correlation, r is close to 1.

2- A perfect correlation of ± 1 occurs only when the data points all lie near to a
     straight line.

3-if r = 0.9, then r ² = 0.81, which means that 19% of the total variation in y remains unexplained.

4- The values of F- distribution can be 0 or negative.

The null hypothesis for one- way ANOVA is that three or more population means are not equal.
