Question
A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly
selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below.
Height (cm) of President
Height (cm) of Main Opponent 169 174 174 168 193 181
182 173 173 191 201 167 e
a. Use the sample data with a 0.01 significance level to test the claim that for the population of heights for presidents and their main opponents, the differences
have a mean greater than 0 cm.
In this example, Ha is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the president's
height minus their main opponent's height. What are the null and alternative hypotheses for the hypothesis test?
Ho: Ha
