Five students received the following test scores: 7, 11, 5, 6, and 11. Calculate the mode,
median, mean, and range of this distribution of scores. Which measure of central
tendency would change the most if an additional test score of 2 were included in the
distribution?
The table lists the scores of eight students on a test to measure anxiety, as well as the
typical number of cigarettes each person smokes daily. Scores on the anxiety test can
range anywhere from a low of 0 (indicating very low anxiety) to a high of 30 (indicating
very high anxiety).

Construct a scatterplot to represent the correlation between smoking and anxiety.
Describe the direction of the correlation and give two possible explanations for it.
At Michigan State University, 32 students are enrolled in class A, 48 students are
enrolled in class B, and 16 students are enrolled in class C. For which of these three
classes is there the greatest probability that more than 75 percent of the students have
blond hair? Explain your answer and indicate why this explanation has relevance for
generalizing appropriately from samples to the larger populations in which you are
interested.
