Answer
$42.1$ words to $64.5$ words
Work Step by Step
We need to find the margin of error. We know the following equation for the margin of error:
$E=t_{0.025}\frac{s}{\sqrt{10}}$, where $s$ is the standard deviation.
Using a standard deviation calculator to find $s$, we find that the error is $11.2$.
Thus, the values can range from $11.2$ below the mean ($42.1$) to $11.2$ above the mean ($64.5$).
