Solve each problem.

1) During a class election a teacher wanted to predict who would win. To do this she took a sample of students from

each class and asked who they would vote for. The results are shown below:

Sample #

Candidate A

Candidate B

Based on the information presented can you infer anything about who will win the election?

Based on the information presented and the small samples gathered it is impossible to

make any meaningful assumptions.

2) A pizzeria owner was trying to determine which types of meat he should stock the most of for his new store. To do

this he asked several pizza eaters what their favorite toppings were. His results are shown below:

Sample #

Pepperoni

20 22 21 22 22 19

Sausage

21 20 18 22 19 18

Ham

20 18 20 22 19 22

Based on the information presented what can you infer about which type of meat he should stock?

Because of the very small discrepancy in the quantities it is unlikely any deduction can

be made about which type of meat he should stock the most of.

3) An ad agency was trying to determine if customers liked blue, green or red packaging better. To do this they took a

sample of customers and polled them. The results are shown below:
