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?
The z-score of a value indicates how many standard deviations it is from the mean. If a value is 2.08 standard deviations greater than the mean, its z-score is simply 2.08. This means the value lies 2.08 standard deviations above the average of the dataset.
Z-Score tells how many standard deviations a measurement is away from the mean.

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

It is a measurement which may, sometimes, be called an extreme observation or an outlier. However, there is no agreed definition for outliers.
The absolute uncertainty of a screw gauge measurement is typically the smallest division on the scale divided by 2. This value represents the smallest increment in measurement that can be confidently distinguished using the device.
