Question
Problem 6. True (T) and False (F) Problems: [2x5 10 points] I ] The median of a data set must be one of the actual number in a given data set. [ ] There are 75% of observations will be ranked below the first quantile value in a given data set.

I ] Since the median is more sensitive than the mean, so mean value can be a better representation t a given data set including a community's overall wealth or poverty level. I 1 According to the central limit theorem (CLT), most quality measurements can be assumed to be normally distributed if the quality measurement understood as the results/summation of many qual contributing factors.Explanation / Answer
