Solve each problem.

1) In a library there was a donation box for books. A librarian wanted to estimate how many fiction and how many

non-fiction books were in the box so she pulled out a sample. The results are shown below:

Sample #

Fiction

Non-Fiction

Based on the information presented can you infer anything about the types of books donated?

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

26 24 23 25 23 23 20

Sausage

34 34 31 32 30 31 33

Ham

41 38 39 38 38 38 40

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

Based on the information presented he should stock more Ham than Pepperoni or

Sausage.

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:

Sample #

Red

21 18 18 18 21

Green

18 18 20 20 21

Blue

22 19 20 19 18

Based on the information presented can you infer anything about which color is liked the best?

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

be made about the color customers liked.
