a. We have the systolic blood pressures by gender of a large number of elderly people. Our statistical question is, “What percentage of these people have blood pressure over 130 mmHG?”

b. We have demographic data on everyone who bought their ticket to a local football game online. Our statistical question is, “Which zip code had the lowest participation from women?”
