Z-Score.
How many standard deviations is 16.50 from the mean?
The "z-score" is derived by subtracting the population mean from the measurement and dividing by the population standard deviation. It measures how many standard deviations the measurement is above or below the mean. If the population mean and standard deviation are unknown the "t-distribution" can be used instead using the sample mean and sample deviation.
You can't average means with standard deviations. What are you trying to do with the two sets of data?
standard deviations
Z-Score tells how many standard deviations a measurement is away from the mean.
No, no measurement we can ever do will be entirely free of uncertainties. In some measurements the uncertainties might be negligible however. In any best precise & accurate measurement there will be minimum uncertainty equal to h/2pie, that's in accordance to Heisenberg's uncertainty principle.

The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.
the Z score, or standard score.

It is a measurement which may, sometimes, be called an extreme observation or an outlier. However, there is no agreed definition for outliers.
Life is full of uncertainties. We have no plans, the uncertainties are part of the fun.
