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
180
184
182
178
187
181
 
Height (cm) of Main Opponent
165
181
182
168
188
183
 
a. Use the sample data with a
0.05
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,
μd
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?
 
H0​: μd (Which of the 4 options below)
less than<
greater than>
equals=
not equals≠
 
cm: (do not round)
 
 
H1​: μd(which of the 4 options)
equals=
greater than>
less than<
not equals≠
cm: (Type integers or decimals. Do not​ round.)
