Question

120 casino patrons, were interviewed as they left the casino. 36 of them said they spent most of the time playing the slots. 36 of them said they played blackjack. 18 said they played craps. 6 said roulette. 6 said poker. The rest were not sure what they played the most. Construct a Pareto chart to depict the gaming practices of the group of casino goers. Choose the vertical scale so that the relative frequencies are represented.

Answer 1

Total casino patrons 120

Players playing slots = 36

players playing blackjack = 36

players playing craps = 18

players playing roulette = 6

players playing poker = 6

others = 120 - 36 - 36 - 18 - 6 - 6 = 18

Here is the frequency and relative frequency table given below.

Game	Freq.	Rel.Freq.	Cumu.Freq.
Slots	36	0.30	0.30
Blakjack	36	0.30	0.60
craps	18	0.15	0.75
roulette	6	0.05	0.80
Poker	6	0.05	0.85
others	18	0.15	1.00
Sum	120	1

Now with the excel we can draw a pareto chart.
