Student researchers wanted to see if a person’s reaction time is slower if they use their nondominant hand to click a computer mouse compared to using their dominant hand. The researchers had a computer program that would display a red circle. When it changed to yellow, the subjects were to click the mouse as fast as they could and the computer would calculate the reaction time. Researchers had their subjects find their reaction time with their dominant hand (e.g., right hand for right handers) and also with their nondominant hand. They randomly determined which hand was tested first. The reaction times (in seconds) for the subjects for each condition can be found in the data file Reaction Times.
a. What is the explanatory and what is the response variable in this study?
b. Write down the hypotheses in either words or symbols.
c. Put the data into the Matched Pairs applet. Just by looking at the graphs in the applet, does it appear that reaction time is significantly slower with the nondominant hand? Explain.

d. What is the value of the statistic that will be used in the study and what does it represent.
e. Randomize at least 1,000 times to develop a null distribution and determine a p-value.
f. Is there strong evidence that reaction times are slower when people use their nondominant hand?
