JUST QUESTION 16 PLEASE

Extracted text: Here are some formulas to help: SP SP =E XY – - ΣΧΣΥ (EY)? SS, = EY? r = SS = Ex² Ex} SSx xSSy n n Use this set of data to answer questions #1 - #17.

What is the value of Sum of Products (SP)? (SHOW YOUR WORK) 7. What is the value of SSx? (SHOW YOUR WORK) 8. What is the value of SSy? (SHOW YOUR WORK) 9. Calculate the Pearson Correlation Coefficient (r): (SHOW YOUR WORK) 10. Sketch a scatterplot for these data: 11. How many degrees of freedom (df) are in this study? 12. If you are doing a two-tailed test and alpha = .05, find the critical value of r from the table: %3D 13. What is your decision regarding the null hypothesis? Reject or Fail to Reject 14. How did you make the determination in Question #13? 15. Is there a significant correlational relationship between X and Y? Yes or No 16. If the Pearson Correlation Coefficient that you calculated in #9 remains the had 4 more participants (n = 11), what would your decision be? Reject or Fail to Reject same, but you %3D
