Answer:
No teen sent texts fewer than 1630 or more than 1854 texts in a month
Explanation:
margin of error gives the difference that may come in the sample results from the actual population results.
Given:
Average teen sends 1742±112 texts per month
here ±112 is margin of error, calculating maximum difference:
1742+112=1854
1743-112=1630
No teen sent texts fewer than 1630 or more than 1854 texts in a month !
