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.
The probability of the mean plus or minus 1.96 standard deviations is 0. The probability that a continuous distribution takes any particular value is always zero. The probability between the mean plus or minus 1.96 standard deviations is 0.95
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 Z score, or standard score.
95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
95% is within 2 standard deviations of the mean.

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