Textbook Question
Chapter 2, Problem 75CRE
Choosing a Graph For each situation, describe the type of statistical graph that could be made to answer the statistical question posted.
a. We have the systolic blood pressures by gender of a large number of elderly people.
Our statistical question is, “What percentage of these people have blood pressure over 130 mmHG?”
b. We have demographic data on everyone who bought their ticket to a local football game online.
Our statistical question is, “Which zip code had the lowest participation from women?”

Suppose that a driver's test has a mean score
of 7 (out of 10 points) and standard deviation
0.5.
a. Explain why you can reasonably assume
that the data set of the test scores is
mound-shaped.
b. For the drivers taking this particular test,
where should 68 percent of them score?
c. Where should 95 percent of them score?
d. Where should 99.7 percent of them score?
S

Can the mean of a data set be higher than
most of the values in the set? If so, how? Can
the median of a set be higher than most of
the values? If so, how?
