Can you explain step by step. Can I resolve this problem on the calculator TI84 Texas Instruments.
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 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?

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 won50% of the elections.
In this case, greater height to be an advantage for presidential candidates because the confidence interval include 50%.
A.
n = 20
No. of presidents who are taller than their opponents = 9 (I have not included the data where the president and the opponent were of the same height)
= 9/20
= 0.45
Confidence Interval:
i.e. [23.2%, 66.8%]
