I can describe the effect of adding,
subtracting, multiplying by, or
dividing by a constant on the shape,
center, and spread of a distribution
of data.
I can approximately locate the
median (equal-areas point) and the
mean (balance point) on a density
curve.
I can use the 68–95–99.7 rule to
estimate the percent of
observations from a Normal
distribution that fall in an interval
involving points one, two, or three
standard deviations on either side
of the mean.
I can use the standard Normal
distribution to calculate the
proportion of values in a specified
interval.
I can use the standard Normal
distribution to determine a z-score
from a percentile.

I can use Table A to find the
percentile of a value from any
Normal distribution and the value
that corresponds to a given
percentile.
I can make an appropriate graph to
determine if a distribution is bellshaped.
I can use the 68-95-99.7 rule to
assess Normality of a data set.
I can interpret a Normal probability
plot
