Find the class boundaries midpoints and widths for each class. a. 12 18 b. 56-74

width :

a)11.5-18.5= -7

b)55.5-74.5=-19

c)694.5-704.5=-10

d)135.5-15.2=120.3

e)214.5-4.43= 210.07

class boundiries :

a)11.5-18.5

b)55.5 -74.5

c)694.4 - 705.5

d)135.5 -15.2

e)214.5 -4.43

mid points :

a)12+18/2 =15

b) 56+74/2 = 115

c)615+704 /2 =700

d)136+14.7/2 =75.35

e)215+3.93/2 = 109.465
