Refer to the data set of 20 randomly selected presidents given below. 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
Construct a 95% confidence interval estimate of the percentage of presidents who were taller than their opponents.
If greater height was an advantage, then taller candidates should have won (more than,less than,exactly) 50% of the elections. In this case, greater height (appears,does not appear) to be an advantage for presidential candidates because the confidence interval (does,does not) include 50%.
