How many standard deviations is 16.50 from the mean?
You can't average means with standard deviations. What are you trying to do with the two sets of data?
standard deviations
95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
You want some measure of how the observations are spread about the mean. If you used the deviations their sum would be zero which would provide no useful information. You could use absolute deviations instead. The sum of squared deviations turns out to have some useful statistical properties including a relatively simple way of calculating it. For example, the Gaussian (or Normal) distribution is completely defined by its mean and variance.
This statement is true. Our eardrums are moved by sound pressure deviations we measure as sound pressure level (SPL) in decibels.

The sum of standard deviations from the mean is the error.

The sum of total deviations about the mean is the total variance. * * * * * No it is not - that is the sum of their SQUARES. The sum of the deviations is always zero.
All minor deviations occurring with two standard deviations under the Gaussian curve are considered normal. Deviations occurring outside of two standard deviations are considered abnormal.
It would be useful to know what the deviations were from.
How many standard deviations is 16.50 from the mean?
Deviations in homeostasis refer to changes in the body's internal balance or stability. These deviations can be caused by various factors, such as illness, stress, or environmental changes. The body responds to these deviations through regulatory systems to restore balance and maintain optimal function.
No, a standard deviation or variance does not have a negative sign. The reason for this is that the deviations from the mean are squared in the formula. Deviations are squared to get rid of signs. In Absolute mean deviation, sum of the deviations is taken ignoring the signs, but there is no justification for doing so. (deviations are not squared here)
For which measure of central tendency will the sum of the deviations always be zero?
