Show calculations for table and show all work.
Remember to show all of yo work for each pr em to receive full credit! 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 3 1 4 3 5 4.20 4.40 2.78 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. YN Sum = df= r rcrit = 4. In one sentence APA formatted, state your conclusion about the relationship between junk food consumption and grumpiness.
