Cerve run cre The following data represents students' measured level of grumpiness (Y) and their score on a measure of junk food consumption (X) for 10 sampled students: Junk Food (X) Grumpiness (Y) X-X Y-Y 7 6 6 4 9 9 4 1 6 7 1 3 1 2 4 1 3 4.20 2.78 3 4 5 4.40 2.41 Mean Std. dev. 3. Is this correlation significant? (Circle one; use a non-directional test) 1. Complete the missing cells in the table and use this to compute the covariance between junk food consumption and grumpiness. CoVxy = (X-X)*(Y-Y) 2. Use the information provided and your covariance above to compute the correlation between junk food consumption and grumpiness. Y N Sum = df= r rcrit = 4. In one sentence APA formatted, state your conclusion about the relationship between junk food consumption and grumpiness.
