Extensive monitoring of a computer time-sharing system has
suggested that response time to a particular editing command is
normally distributed with a standard deviation of 25 milliseconds.
A new operating system has been installed, and we wish to estimate
the true average response time 𝜇 for the new environment. Assuming
that response times are still normally distributed with 𝜎 = 25,
what sample size is necessary to ensure that the resulting 95% CI
has a width of (at most) 10?
