Examining Samples

Solve each problem.

1) In a lake there are 3 types of fish: minnows, goldfish and sunfish. A fisherman wanted to estimate how many of

each type there were. He scooped up several nets full and recorded his results (shown below).

Sample #

minnows

goldfish

sunfish

Based on the information presented can you infer anything about the number of different types of fish in the lake?

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

make any meaningful assumptions.

2) In order to determine which type of sweets he should keep the most of in his shop a baker logged every 5th

customers order. His findings are shown below:

Sample #

30 35 30 33 30

Brownies

41 44 44 40 41

Cupcakes

52 48 49 48 51

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

Based on the information presented he should keep more Cupcakes than Cookies or

Brownies.

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

28 32 31 28 32 32 30

Green

30 29 31 30 30 28 32

Blue

28 29 31 31 31 31 29

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.
