Analysis

(n) For the simulation you created, map the components to the research study:

Null hypothesis =
One repetition =
Statistic =

	The previous question is pretty important, ask if you are not sure.

(o) Confirm that the mean of your dotplot results is approximately zero. Explain why it makes sense for the observations in this dotplot to have a mean of about zero.

 

(p) Interpret the resulting p-value in context:

Use the pull-down menus in the four blanks to fill in the following sentence interpreting your approximate p-value:

Under the assumption that Choose one the yawn seed does not make a difference yawning is contagious , if we repeated Choose one the research study the random assignment process the random sampling process many, many times, we would get results as extreme or more extreme than Choose one 0 .136 , in about Give number % of the repetitions.

	The previous question is pretty important, ask if you are not sure.

(q) Evaluate the p-value: Does this p-value provide strong evidence against the null hypothesis? Clearly indicate how you are deciding. [Remember the guidelines from Lab 1.]
