How many standard deviations is 16.50 from the mean?
That depends on what the standard deviation is.
95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
Z-Score.
It is mean + 2*standard deviation.
In a normal distribution, approximately 68% of scores fall within one standard deviation of the mean (between -1 and +1 standard deviations). About 95% of scores fall within two standard deviations (between -2 and +2 standard deviations). Therefore, the percentage of scores that falls specifically between the mean and -2 to 2 standard deviations is about 95% minus the 50% that is below the mean, resulting in approximately 45%.
Z-Score tells how many standard deviations a measurement is away from the mean.
That depends on what the standard deviation is.
The sum of standard deviations from the mean is the error.
It is 1.28

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