11. Refer to the accompanying data set of 20 randomly selected presidents. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not? 1 Click the icon to view the table of heights. Construct a 95% confidence interval estimate of the percentage of presidents who were taller than their opponents. %

Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not? 1 Click the icon to view the table of heights. Construct a 95% confidence interval estimate of the percentage of presidents who were taller than their opponents. % <p<[ (Round to one decimal place as needed.) % If greater height was an advantage, then taller candidates should have won (1) 50% of the elections. In this case, greater height (2) to be an advantage for presidential candidates because (3). 1: President and Opponent Heights (cm) PRESIDENT HEIGHT HEIGHT OPP Harrison 168 180 Wilson 180 182 Pierce 178 196 G.
