A QQ plot shows if the (a)____ is normally distributed. If the points roughly follow the identity line, we can assume that the sample was drawn from a (b)____ that is normally distributed, which is a key assumption that must be made to perform inferences for poplation means. (a) Choice 1 of 6: sample mean Choice 2 of 6: sample of quantitative observations Choice 3 of 6: sample standard deviation Choice 4 of 6: population standard deviation Choice 5 of 6: population of quantitative observations Choice 6 of 6: population mean Grading comment: (b) Choice 1 of 6: sample standard deviation Choice 2 of 6: population mean Choice 3 of 6: sample mean Choice 4 of 6: population of quantitative observations Choice 5 of 6: sample of quantitative observations Choice 6 of 6: population standard deviation
