Give me an example of $1.$ For example, let's say my height is $72\mathrm{.}845$ inches $($this is an online environment, so you expect a bit of a fudge in the personal data$).$ Using the Excel standardize function, my z score would be $1\mathrm{.}282,$ and using the normdist function, the probability of someone being shorter than I is $90\%,$ which means only $10\%$ are taller.
