Note: If it is a decimal number with two or more than two places, leave only two decimal places after the decimal point and do not round.
If it is a negative correlation, please do not forget to include the negative sign.

Q7. What is the coefficient of determination? Q11. State which correlation coefficient (Pearson, Spearman, point-biserial, or phi) should be used given the following information. Both factors are interval or ratio scale. Both factors are ranked. One factor is dichotomous, and the other factor is continuous. Both factors are dichotomous. Q13. State whether each of the following is an example of a positive correlation or a negative correlation. Higher education level is associated with a larger annual income. Increased testosterone is...
Question 24 2 pts Arnold calculates a Pearson correlation and obtains a value of -1.07. By definition, this implies he has made a mistake in his calculations there is a negative and strong relationship between the two variables the distribution of scores for the variables are negatively skewed he will not reject the null hypothesis Question 25 2 pts For which of these research situations would you most likely calculate a Pearson correlation? X variable = political affiliation; Y variable...

Suppose that over the past 30 years during any given week of the major-league season, an average of µ = 12 players are hit by wild pitches. Assume that the distribution is normal with a standard deviation of σ =3. For a sample of n = 4 weeks, in which the daily temperature was extremely hot, the weekly average of hit-by- pitch players was M = 15.5. Are players more likely to get hit by pitches during hot weeks? Use...

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna).† Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is x = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution...
Let ρ represent the true population coefficient of correlation of two variables X and Y . Suppose you want to test the hypothesis that ρ = 0. Explain how you would test this hypothesis. [Hint: by the relationship between b1 and rXY ]
