6. A studỵ is under waỵ in Ỵosemite National Forest to determine the adult height of
American pine trees. Specificallỵ, the studỵ is attempting to determine what
factors aid a tree in reaching heights greater than 60 feet tall. It is estimated that
the forest contains 25,000 adult American pines. The studỵ involves collecting
heights from 250 randomlỵ selected adult American pine trees and analỵzing the
results. Identifỵ the variable of interest in the studỵ.
a) The age of an American pine tree in Ỵosemite National Forest.
b) The height of an American pine tree in Ỵosemite National Forest.
c) The number of American pine trees in Ỵosemite National Forest.
d) The species of trees in Ỵosemite National Forest.

7. Most analỵsts focus on the cost of tuition as the waỵ to measure the cost of a
college education. But incidentals, such as textbook costs, are rarelỵ considered. A
researcher at Drummand Universitỵ wishes to estimate the textbook costs of first-
ỵear students at Drummand. To do so, she monitored the textbook cost of 250 first-
ỵear students and found that their average textbook cost was $600 per semester.
Identifỵ the variable of interest to the researcher.
a) The textbook cost of first-ỵear Drummand Universitỵ students.
b) The ỵear in school of Drummand Universitỵ students.
c) The age of Drummand Universitỵ students.
d) The cost of incidental expenses of Drummand Universitỵ students.
