3) Pulserate
Ninety-two students in a statistics class performed the following experiment. Each student recorded his or her
pulse rate and then flipped a coin. If the coin came up heads, the student ran in place for a minute. Otherwise,
the student did not. The student then took his or her pulse rate again. The pulse rates and related information
about the students are recorded in the following chart.

4) Peruanos
Anthropologists wanted to determine the long-term effects of altitude change on human blood pressure. They
measured the blood pressures of a number of Peruvians native to the high Andes mountains who had since
migrated to lower climes. Previous research suggested that migration of this kind might cause higher blood
pressure at first, but over time blood pressure would decrease. The subjects were all males over 21, born at
high altitudes, with parents born at high altitudes. The measurements included a number of characteristics to
help measure obesity: skin-fold and other physical characteristics. Systolic and diastolic blood pressure are
recorded separately; systolic is often a more sensitive indicator. Note that this is only a portion of the data
collected.
