Analysis

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

Null hypothesis =
One repetition =
Statistic =

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

 

(m) 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 treatment given does not make a difference swimming with dolphins is beneficial , 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 .467 , in about Give number % of the repetitions.

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

(n) 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.]
