Question 1

Which of the following examples would most likely be subject to survivor bias?

Accepted Answer

A)  a study that randomly sampled an equal number of 40-year old men and 60-year old men to measure incidences of Type 1 diabetes 
B)  a study that randomly sampled flood victims whose homes were destroyed to see if they were likely to rebuild their homes on the same property 
C)  a study that randomly sampled first-year law-school students to see how many survived to make it to their second year in law school 
D)  a study that randomly sampled men and women who suffered food poisoning from dining at a specific fast-food restaurant chain to determine the incidence of continued patronage of that particular chain of restaurants

Question 2

Refer to the information provided in Scenario 22.3 below to answer the question(s) that follow.
SCENARIO 22.3: Consider a local high school that has 300 sophomores considered to be at-risk students. A privately-sponsored after-school sports program has been established to try to help at-risk students succeed in finishing high school. The local government wants to know if this program reduces the students' probability of dropping out of high school before the end of their junior year, and decides to randomly sample 150 of the 300 at-risk sophomores and invite them to attend the after-school program at no cost. 100 students accept the invitation, and by the end of their junior year, the drop-out percentage of the 100 students who attended the program was lower than the drop-out percentage of the 200 students who did not attend the program.
-Refer to Scenario 22.3. To use the intention-to-treat procedure to measure the effect of the after-school program, you would need to compare

Accepted Answer

A)  the drop-out percentage of the 100 students who attended the program to the drop-out percentage of the 200 students who did not attend the program. 
B)  the drop-out percentage of the 100 students who attended the program to the drop-out percentage of the 50 students who were offered the program but chose not to attend. 
C)  the drop-out percentage of the 150 students who were offered the program to the drop-out percentage of the 150 students who were not offered the program. 
D)  the drop-out percentage of the 50 students were offered the program but chose not to attend to the drop-out percentage of the 150 students who were not offered the program. 
A)  the drop-out percentage of the 100 students who attended the program to the drop-out percentage of the 200 students who did not attend the program. 
B)  the drop-out percentage of the 100 students who attended the program to the drop-out percentage of the 50 students who were offered the program but chose not to attend. 
C)  the drop-out percentage of the 150 students who were offered the program to the drop-out percentage of the 150 students who were not offered the program. 
D)  the drop-out percentage of the 50 students were offered the program but chose not to attend to the drop-out percentage of the 150 students who were not offered the program.

Question 3

Refer to the information provided in Table 22.3 below to answer the question(s) that follow.
Table 22.3
 $$\begin{array} { | c | c | c | } 
\hline \text { Point } & \begin{array} { c } 
\text { Aggregate } \
\text { Income } ( \boldsymbol { Y } )
\end{array} & \begin{array} { l } 
\text { Aggregate } \
\text { Consumption } ( \boldsymbol { C } )
\end{array} \
\hline \boldsymbol { A } & 15 & 19 \
\hline \boldsymbol { B } & 30 & 23 \
\hline C & 45 & 27 \
\hline D & 60 & 31 \
\hline E & 75 & 35 \
\hline F & 90 & 39 \
\hline
\end{array}$$ The data in the table was used to estimate the following consumption function: C = 20 + 0.2Y
-Refer to Table 22.3. The error for point A is equal to

Accepted Answer
