Part II - Utilize data from class activity 10.What are the null and alternative hypotheses for the correlation between the variables (time spent exercising (x) & heart rate (y))

11.What is Pearson's r for the exercise time versus heart beats per minute in the class data?

a. Interpret this correlation in terms of the strength and direction.

12.Is the correlation significant? (hint: you must use table B.4 in your text - assume alpha 0.05) Please record the critical value and the obtained value below.

b. What is your experimental conclusion (this refers to your null/alternative hypotheses) - state conclusions in a sentence.

13.What is the coefficient of determination? c. Interpret the coefficient of determination in a sentence:

14.What is the coefficient of alienation? d. Interpret the coefficient of alienation in a sentence:

15.What are the null and alternative for the regression equation?

16.What is the regression equation?

e. Interpret the regression equation in a sentence:

17.Is the result significant? f. Report the values you are comparing:

g. Report your experimental conclusion (this refers to the null/alternative) :

18.Predict the number of heart beats per minute if the number of seconds of seconds of activity was 27.
