Reconsider the study mentioned in the previous exercise about an investigation of whether men with children tend to live longer, on average, than men without children.

a. Define (in words) the parameters of interest of this study. Also, assign symbols to the parameters.
b. Express the null and alternative hypotheses for testing whether men with children tend to live longer, on average, than men without children. Use words only.
c. Express the null and alternative hypotheses for testing whether men with children tend to live longer, on average, than men without children. Use the symbols defined in part (a).
d. Give detailed, step-by-step instructions on how one could conduct a tactile simulation to generate a p-value to test the hypotheses stated in parts (b) and (c). Be sure to include details on the following:
• Would the simulation involve coins, dice, or index cards?
• How many tosses, rolls, or cards would be used?
• How many sets of tosses, rolls, or shuffles would you observe?
• What would you record aft er every repetition?

• How would you compute the p-value?

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.
