Question 1

This experiment is best described as a(n):
A) randomized survey.
B) completely randomized design.
C) factorial treatment design carried out in a completely randomized experimental design.
D) observational study.

Accepted Answer

The experiment is described as a factorial treatment design, which involves manipulating two or more independent variables (factors) in order to observe their effects on the dependent variable. This design is being carried out in a completely randomized experimental design, meaning participants are randomly assigned to each combination of treatments. Therefore, option C is the best choice.

Question 3

A researcher wants to investigate whether there is a significant difference in the average age of instructors, assistant professors, associate professors, and full professors at a university. The faculty members were selected at random and their ages were recorded. Use the collected data to complete the ANOVA chart given below 
$\begin{array}{l}
\text { Raw Data }\
\begin{array}{cccc}
\hline \text { Instructors } & \begin{array}{c}
\text { Assistant } \
\text { Professors }
\end{array} & \begin{array}{c}
\text { Associate } \
\text { Professors }
\end{array} & \text { Professors } \
\hline 26 & 28 & 45 & 58 \
32 & 32 & 48 & 56 \
29 & 36 & 52 & 62 \

Question 5

A diet centre wants to test three different methods for losing weight to determine if the average weight loss (reported in pounds/week) for each method is the same. The results for the three methods are given below. Assuming that there is a significant difference between the three methods, use the Tukey test to determine if there is a significant difference between each pair of methods. Let $\alpha =0.05$
$\begin{array}{lll}
\text { Liquid Diet } & \text { Low-Calorie Diet } & \text { Low-Calorie Diet \& Exercise } \
5 & 3 & 3 \
2 & 2 & 3 \
1 & 2 & 4 \
2 & 3 & 5 \
3 & 4 & 3 \
4 & 1 & 4
\end{array}$
