26. Calculate each value requested for the following set of scores. a. ΣX X Y b. ΣY 1 6 c. ΣXΣY 3 0 d. ΣXY 0 –2 2 –4 27. Use summation notation to express each of the following calculations. a. Add 3 points to each score, then find the sum of the resulting values. b. Find the sum of the scores, then add 10 points to the total. c. Subtract 1 point from each score, then square each of the resulting values. Next, find the sum of the squared numbers. Finally, add 5 points to this sum. 28. Describe the relationships between a sample, a population, a statistic, and a parameter.
