Construct an interval that will include the middle 68.26% of the data set above. (2 points) Consider using Empirical Rule: 68.26% means within the range of: s x Lower Interval = 757 . 20 443 . 6 2 . 27 s x Upper Interval = 643 . 33 443 . 6 2 . 27 s x g) Count how many data actually fall into the interval in part f), and what is the percentage of the data?
