___________% of data values fall below the mean and ___________% of data values fall above the mean.
If 68% of values fall within 1 standard deviation of the mean, then ____________% fall between the mean and +1 standard deviation
and _____________% fall between the mean and -1 standard deviation.
If 68% of the values fall within 1 standard deviation, then a total of ___________% fall more than one standard deviation from the
mean. This means that ___________% of values are more than 1 standard deviation above the mean and ___________% of values
are more than 1 standard deviation below the mean.
If 95% of the values fall within 2 standard deviations of the mean, then a total of ___________% fall more than 2 standard deviations
from the mean. This means that ____________% are more than 2 standard deviations above the mean and ___________% are more
than 2 standard deviations below the mean.
If 95% of values fall within 2 standard deviations, then __________% fall between 0 and 2 deviations above the mean and
__________% fall between 0 and 2 deviations below the mean.
If 99.7% of values fall within 3 standard deviations of the mean, then __________% fall between 0 and 3 deviations above the mean
and __________% fall between 0 and 3 deviations below the mean.
If 34% falls between 0 and 1 deviation and 47.5% falls between 0 and 2 deviations, then ___________% falls between 1 and 2
deviations.
If 49.85% falls between 0 and 3 deviations and 47.5% falls between 0 and 2 deviations, then ___________% falls between 2 and 3
deviations.
