Construct a frequency and relative frequency distribution for the data given below. Let each class have a width of 2 and begin the first with 0. 0 1 1 1 1 2 2 2 2 2 2 3 3 3 4 5 6 6 7 7 8 8 8 9 10My question is would the class with be 0-1 2-3 4-5 6-7 8-9 10-11.......is this right even though 11 is not actually written in the list of numbers?Also how would you find the mean for this frequency distribution?
