Given a set of data, make a vertical bar chart
showing the frequencies of occurrences of
equal intervals of the data.
Box Plot
Given a set of data, plot the minimum, first
quartile, median, third quartile, and maximum

when the population standard deviation is
estimated by the standard error
Confidence Interval – Two Means
Find the confidence Interval for the difference
of two sample means when the standard
deviation is estimated by the standard error
Hypothesis Test – One Proportion
Given one sample proportion, find the p-value
that it is a sampling variation of a given value
Hypothesis Test – Two Proportions
Given two sample proportions, find the p-value
that their difference is a sampling variation of
a true difference of zero.
Hypothesis Test – Mean
Given one sample mean, find the p-value that it
is a sampling variation of a given value.
Hypothesis Test – Two Means
Given two sample means, find the p-value that
their difference is a sampling variation of a
true difference of zero.
Hypothesis Test – The Power of the Test
Given a null hypothesis, and alpha level, and
assumed true alternate hypothesis, find the
