Examining Samples

Solve each problem.

1) 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

32 29 32 31 30

Green

32 32 31 30 29

Blue

30 32 32 32 28

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.

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 #

Brownies

61 58 62 58 61 61

Cupcakes

46 45 43 42 46 42

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

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

Cupcakes.

3) An animal control employee wanted to estimate how many people owned cats and how many owned dogs. To do

this he polled the first few houses in several neighborhoods. His findings are shown below:

Sample #
