Answer:
the range of possible weights for the letters is 98-105 ounces.
Explanation:
To determine whether 101 ounces is a reasonable estimate for the weight of 25 letters that each weigh between 3.92 ounces and 4.2 ounces, we need to calculate the range of possible weights for the letters.
The minimum weight for the letters is 25 * 3.92 ounces = 98 ounces. The maximum weight for the letters is 25 * 4.2 ounces = 105 ounces. Therefore, the range of possible weights for the letters is 98-105 ounces.
Since 101 ounces falls within this range, it is a reasonable estimate for the weight of the letters.
