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 ($64.5$).
