1. Use the table below to answer the following questions. The following observations were taken for five students measuring math and reading level. The researcher was interested in whether math levels were associated with reading level. (5 points) Subject # Math Level Reading Level 6 1 6 2 12 14 3 5 7 4 8 5 9 9 9 a. State the null and alternative hypothesis for the following set of data. b. By hand or with excel, draw a scatterplot using the above data with math level on the x- axis and reading level on the y-axis. (Make sure that you label the axis correctly). c. Is the relationship between weight and income negative or positive? d. By hand, compute the Pearson correlation coefficient for math and reading level. Show your work for each step we talked about in class (SP, SS, SS, and r). e. Describe the relationship between math level and reading level. f. What is the Coefficient of Determination?
