Analysis
(m) For the dotplot you generated, what the observational units and variable are for the graph? (Hint: What would you do to add another dot to the dotplot??)

The previous question is important; ask for help if you are not sure. |
(n) Around what value is this dotplot centered? Does it make sense for this dotplot to be centered around this value? Why or why not?
(o) Interpret the resulting p-value in context:
Use the pull-down menus in the four blanks to fill in the following sentence interpreting your proportion from part k.
Under the assumption that , if we repeated many, many times, we would get results as extreme or more extreme than , in about % of the repetitions.

(p) Evaluate the resulting p-value. [Remember the guidelines from Lab 1.] Is this p-value small enough so that you would consider such an outcome as the Mythbusters investigators actually obtained (or more extreme) surprising under the null hypothesis that yawn seeding is not effective? Clearly indicate how you are deciding.
