Question

A report says that the average amount of time a 10-year-old American child spends playing outdoors per day is between 19.52 and 25.2 minutes. What is the margin of error in this report?

Answer 1

The margin of error in this report is 2.84 minutes.

Step-by-step explanation:

The margin of error in a report represents the range of values within which the true population parameter is likely to fall. It provides a measure of the precision of the estimate.

To calculate the margin of error, we can use the formula:

Margin of Error = (1/2) * (Upper Bound - Lower Bound)

Given that the upper bound is 25.2 minutes and the lower bound is 19.52 minutes, we can substitute these values into the formula:

Margin of Error = (1/2) * (25.2 - 19.52)

= (1/2) * 5.68

= 2.84 minutes

Therefore, the margin of error in this report is 2.84 minutes.
