5. Recall that 60 randomly selected shoppers have rated a new bottle design for a popular soft drink. The data are given below. 34 33 33 29 26 32 25 27 33 22 24 30 20 34 31 32 28 30 31 31 31 28 33 31 32 32 30 34 32 30 33 28 25 32 33 27 32 33 32 29 32 30 35 33 31 33 29 27 34 31 28 26 29 32 34 30 32 31 29 33 a. Find the number of classes that should be used to construct a frequency distribution and histogram fore the bottle design ratings. b. If we round up to the nearest whole rating point, show that we should employ a class length equal to 3. c. Define the non-overlapping classes for a frequency distribution.
