Examining Samples

Solve each problem.

1) 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

41 42 41 39 41 42 39 41

Sausage

39 42 42 38 42 39 42 38

Ham

39 38 41 42 38 40 40 39

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.

2) A store manager was trying to figure out how many people did their shopping online compared to doing it in

stores. To do this she polled several houses in the nearby neighborhoods. The results are shown below:

Sample #

Online

In-Store

Based on the information presented can you infer anything about the number of people who did their shopping

online vs. in-store?

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

make any meaningful assumptions.

3) 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

34 34 32 30 30 33 34

Non-Fiction

41 41 41 40 42 38 41

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

Based on the information presented there will be 20% more Non-Fiction books donated.
