7. Consider the set of all students enrolled in your statistics course this
term. Suppose you are interested in learning about the current grade
point averages (GPAS) of this group.
a. Define the population and variable of interest.
b. Is the variable qualitative or quantitative?
c. Suppose you determine the GPA of every member of the class.
Would this represent a census or a sample?
d. Suppose you determine the GPA of 10 members of the class. Would
this represent a census or a sample?
e. If you determine the GPA of every member of the class and then
calculate the average, how much reliability does this have as an
"estimate" of the class average GPA?
f. If you determine the GPA of every member of the class and then
calculate the average, will the number you get necessarily be the
same as the average GPA for the whole class? On what factors
would you expect the reliability of the estimate to depend?
