What are the null and alternative hypotheses for an ANOVA Test comparing population means? (Note that the selections are automatically randomized and the Alternative Hypothesis may be listed first.)

The correlation coefficient, r, can be used to decide if data has a strong linear relationship. We always have -1≤r≤1{“version”:”1.1″,”math”:”-1≤r≤1″} .  What values of r  indicate the strongest linear relationship to the data. (Select all statements that indicate a strong linear relationship.)
