Name:

Examining Samples

Solve each problem.

1) For a canned food drive there were 3 types of cans vegetables donated: peas, carrots and green beans. To estimate

how many of each type were donated, you pull out a sample. The results are shown below:

Sample #

peas

34 34 34 34 30

carrots

40 41 41 42 40

green beans

51 51 48 49 49

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

Based on the information presented there will be more green beans donated than peas or

carrots.

2) At the football game a vendor was trying to determine if Coke or Pepsi sold better. To do this he asked several

rows of attendees which flavor they bought. His results are shown below:

Sample #

Coke

Pepsi

Based on the information presented what can you infer about the types of soda sold?

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

42 39 42 41 38 38 40

Non-Fiction

38 38 38 39 42 40 41

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

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

be made about the types of books donated.
