Student researchers wanted to see whether a short delay between seeing a list of words and when people were asked to recall them would hinder memorization. The subjects were shown a list of words to memorize for 1 minute and were then given 1 minute to recall as many words as they could. Each subject did this once with no delay between memorizing and recall and another time with a 30-second wait between memorizing and recall. They were randomly assigned the order of the two conditions. The number of words memorized under each condition can be found in the data file MemorizationDelay.
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 the delay significantly hinders memorization? 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 a short delay hinders the memorization process?
