From a recent survey of 1500 households in Canada, the Cable and Telecommunications Association reported that the numbers of HDTVs per household are as follows:
Number of HDTVs | Number of Households |
0 | 120 |

3–4 | 420 |
5 or more | 120 |
Total | 1500 |
The manager at the Best Buy store in Rosemere wanted to find out if the reported results were the same for his city. He decided to sample 100 customers who came into his store last week. He found that 7 households had 0 HDTVs, 55 had 1 to 2 HDTVs, 28 had 3 to 4 HDTVs, and 10 had 5 or more HDTVs. At the 0.10 level of significance, is it reasonable to conclude that the number of HDTVs per household in Rosemere is the same as that reported by the Cable and Telecommunications Association?
