Reconsider the study mentioned in the previous exercises about an investigation of whether men with children tend to live longer, on average, than men without children.
The data are in the file ChildrenandLifespan. 

a. Use an appropriate randomization-based applet to fi nd a p-value to test whether men with children tend to live longer, on average, than men without children. Report and interpret the p-value in the context of the study.

b. Use the p-value to indicate the strength of evidence against the null hypothesis.
c. Calculate an appropriate standardized statistic and interpret the standardized statistic in the context of the study.
d. Use the 2SD method to find a confidence interval for the parameter of interest. Report this interval and interpret the interval in the context of the study.
e. Do the results from the 95% confidence interval agree with your conclusion in part (c)? How are you deciding?
f. Give a full conclusion, including significance, estimation, causation, and generalization.

Data from previous question

Do men with children tend to live longer, on average,than those without? To investigate, a group of Cal Poly students randomly sampled men from the obituaries page on the San Luis Obispo Tribune’s webpage between June and November 2012. For each man selected, they noted the age at which the person died and whether or not the person had any children.
