To find: How many individuals are described in this table.
Expert Solution & Answer
Answer to Problem 6.8CYS
The correct option is (b) 1,918.
Explanation of Solution
Reason for correct answer:
The data shows the number of cell phone users who tends to use social media on their phone and the data is separated according to their age group.
| Social media usage on Phone | Yes | No |
| 18-29 | 228 | 112 |
| 30-49 | 281 | 281 |
| 50-64 | 106 | 481 |
| 65+ | 21 | 408 |
The total number of individuals given in the data is calculated as follows:
Thus, the option (b) 1,918 is correct.
Reason for incorrect answers:
Option (a) 636.
The given option represents the total number of individuals are 636. But, there are 1,918 individuals given in the data.
Option (c) Need more information.
The given option represents the information given is not sufficient enough to find the number of individuals. But, there is sufficient information given in the data to obtain the total number of individuals.
Thus, the Options (a) and (c) are incorrect.
Conclusion:
Thus, the total number of individuals given in the data is 1,918. Thus, the correct option is (b) 1,918.

In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.
