A marketing study was conducted to assess the new bottle designof a popular soft drink. Sixty randomly selected shoppersparticipated and rated the new design. The data are givenbelow:
34 33 33 29 26 33 28 25 32 33
32 25 27 33 22 27 32 33 32 29
24 30 20 34 31 32 30 35 33 31
32 28 30 31 31 33 29 27 34 31
31 28 33 31 32 28 26 29 32 34
32 30 34 32 30 30 32 31 29 33
a. Explain why we need to construct a frequency distribution andhistogram for this data set.
b. Construct a relative frequency distribution and a percentfrequency distribution for the bottle design ratings.
c. Construct a cumulative frequency distribution and cumulativepercent frequency distribution.
