Question
Chapter 6, Problem 6.8CYS
To determine
To find: The number of individuals is described by the two way table.
Expert Solution & Answer
Answer to Problem 6.8CYS
The correct answer is option (b).
Explanation of Solution
Given info:
The two way table shows the responses by permissive school with regards to cell phone.
| Frequency | Forbid |
Allow in school but not in class | Allow in class |
| New | 25 | 19 | 4 |
| Less often | 14 | 31 | 6 |
|
At least several times per week | 14 | 23 | 8 |
| Every day | 97 | 314 | 57 |
Calculations:
Reason for correct answer:
The total number of individuals described by the two way table is,
Reason for incorrect answer:
Option (a): 468 is wrong because the calculated total number of individuals is described by the two ways table is, 612.
Option (c): Need more information is wrong because the calculated total number of individuals is described by the two ways table is, 612.
Conclusion:
Hence, the total number of individuals is described by the two ways table is, 612.

Test d'égalité des espérances: observations pairées
A television news channel samples 25 gas stations from its local area and uses the results to estimate the average gas price for the state. What’s wrong with its margin of error?
You’re fed up with keeping Fido locked inside, so you conduct a mail survey to find out people’s opinions on the new dog barking ordinance in a certain city. Of the 10,000 people who receive surveys, 1,000 respond, and only 80 are in favor of it. You calculate the margin of error to be 1.2 percent. Explain why this reported margin of error is misleading.
