Find the interval $\left[ \mu - z \frac{\sigma}{\sqrt{n}}, \mu + z \frac{\sigma}{\sqrt{n}} \right]$ within which 95 percent of the sample means would be expected to fall, assuming that the sample is from a normal population.\
$\mu = 220, \sigma = 25, n = 45$. (Round your answers to 2 decimal places.)\
The 95% range is from to
