or n? The Range? The class width? Calculate the midpoint of each class 3. The daily sales for Acme Widget are recorded as follows: 91 105 178 98 121 94 240 173 a) Construct a frequency distribution where the first class has the limits 0 to <100. b) What is the value of n? The Range? The class width? Calculate the midpoint of each class Erocks has kent records of the

Answer 1

Formula used for calculations-
n= sum of frequencies
range= maximum limit of the class- minimum limit of the class
class width= lower limit of first class- lower limit of second class
mid point= ( lower limit of the class + upper limit of the class)/2

a) class Interid Frequency Mid 0 Points 0-99 DO-199 200-299 3 ។ 49.5 149.5 249.5 Ef=8 b 1 n = {f=8 8 ii) Class Width = loo-0 =100 111) Range = 299-0 = 299 ik) Mid Points 49.5 149.5, 249.5.
