A continuous random variable, X, is found to be uniformly distributed over the interval 4≤x≤9. What is the probability that a number randomly chosen from this interval is in the interval 3≤x≤8? Give the notation of the distribution and the notation of the probability that would be calculated.

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.)
