(1 pt each) The following are quiz scores from two Algebra 1 Classes. Class 1: $\{68,93,53, 100,77,86,91,88,72,74,66,82\}$ and Class 2: $(77,91,82,68,75,72,85,65,70,79,94,86)$ a. Compare the means of the class scores. Which would you rather be in? Mean Class 1: Mean Class 2: b. Compare the standard deviations. Which class was more consistent in their scores? Std. Dev. Class 1: Std. Dev. Class 2: S.P.PB. 363
