And that is $750. They also tell us that we have a standard deviation of $60. So that means one standard deviation above the mean would be roughly right over here, and that would be 750 plus 60.

$\begingroup$ What standard distribution are you talking about? Do you mean to assume normality? While I regard that as highly dubious - especially in the extreme tails - if we do assume it then that case the percentile of the value you quoted is extremely small; the z-score is $141/16.7\approx 8.44$, so the upper tail area is roughly …

The standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution.Empirical Rule Calculator.
