For a standerd normal distribution, find the percentage of data that are more than 1 standard deviation away from the mean.
Solution
percentage of data that are more than 1 standard deviation away from the mean
x > miu + 1 standard deviation
we know that between miu +/- 1* standard deviation we have 68% of the data
and we know that the normal distribution is symmetric so up to the mean we have 34%
between the mean and 1 standard deviation we have 34% of the data
and we know that up to the mean we have 50% of the data and above the mean 50% of the data
so the percentage of data that are more than 1 standard deviation away from the mean is
50 - 34 = 16%
