B)  5 
C)  5.5 
D)  6 
A)  4

Question 2

Reaction-time (RT) data are often obtained by I/O psychologists when evaluating equipment. RT scores are known to be positively skewed. Suppose a safety-mandated shield on a metal-stamping machine required a new configuration of buttons and levers used for emergency panic stops. Two new configurations are possible and experienced operators are used to evaluate them. Each operator tries both of the two configurations and a mean RT is obtained for each operator. What conclusion should the psychologists reach about the two configurations? $$\begin{array} { c c } 
 { \text { Time in seconds } } \
\text { Configuration A } & \text { Configuration B } \
\hline 1.62 & 1.41 \
1.53 & 1.48 \
1.72 & 1.85 \
1.93 & 1.73 \
1.21 & 1.43 \
1.60 & 1.62 \
1.26 & 1.35 \
1.55 & 1.52 \
1.71 & 1.67
\end{array}$$

Question 9

One common use of statistics is to compile score for each city on a list of cities. Suppose you thought that large cities would rank higher than small cities. To make sure that the age fo the city didn't influence the comparison, you matched each large city with a small one that was founded at about the same time. Which statistic should you use to test your idea about the size of cities and their rank?

B)  Wilcoxon matched-pairs signed-ranks T test

For the 15 animals in the troop, the following order was found (M = male, F = female):M , F , F , F , M , F , M , M , F , F , M , M , M , M , FUse an appropriate test to answer the anthropologist's question.
