Using the same approach as in Section 6.2 with the Multiple Means
applet, you can use this applet to generate possible values of the difference
in sample means under the nullhypothesis by shuffling which response values go
with which explanatory variable values. Check the Show Shuffle Options box and
enter 1,000 for the Number of Shuffles. Press the Shuffle Responses button
(there will be a pause; this is a large data set!). The histogram on the right
is the simulated null distribution for the difference in sample means. Enter
the observed difference in sample means in the Count Samples box and press
Count.

a. Record your estimated p-value.

 b. Fill in the blanks of the following sentence, to
complete the interpretation of the p-value. The p-value of ________ is the
probability of observing ________________________________ assuming
__________________________________.
