Looking for help with the following question

(a) Calculate s. 32, and M for the following set of scores: {8. 7. 5. 5, 5, 4). Assume that you are estimating the population variance and standard deviation. (b) Add a constant 2, to each score in (a). Recalculate s, 32. and M. What was the effect of adding a constant to each score? (c) Multiply each score by 2 in (a). Recalculate s, 32, and M. What was the effect of multiplying by a constant
