2. 2. Suppose a certain scale is not calibrated correctly, E) 1
and as a result, the mass of any object is displayed as
0.75 kilogram less that its actual mass. What is the cor-
relation between the actual masses of a set of objects
and the respective masses of the same set of objects
displaced by the scale?

3. 3. A veterinarian collected data on the weights of 1,000 D) Segmented bar chart
cats and dogs treated at a veterinary clinic. The weight
of each animal was classified as either healthy, under-
weight, or overweight. The data are summarized in the
table.

4. 4. A program exists to encourage more middle school
students to major in math and science when they go
to college. The organizers of the program want to esti-
mate the proportion of students who, after completing
the program, go on to major in math or science in
college. The organizers will select a sample of students
from a list of all students who completed the program.
Which of the following sampling method describes a
stratified random sample?
A) Select all female students on the list.
B) Randomly select 50 students on the list.
C) Randomize the names on the list and then select
every tenth student on the randomized list.
D) Randomly select 25 names from the female stu-
dents on the list and 25 names from the male students
on the list.
E) Randomly select 50 students on the list who are
attending college.
