A | B | C | D Problem 3] A popular theory is that presidential candidates have an advantage if they are taller than their opponents. Use the provided data set and a 0.05 significance level to test the claim that for the population of heights of presidents and their opponents, the differences have a mean greater than 0 cm. Steps for Hypothesis Testing Step 1} Identify the Claim Step 2} Identify the Null and Alternative Hypothesis Null Hg Alternative Ha Step 3} Select the Significance Level a: Step 4} Determine the distribution and identify the test statistic and draw the graph. Distribution Statistic Step 5} Calculate the pvalue or critical value and make a decision pvalue Step 6} State the conclusion G H Height {cm} Height {cm} ofPresident ofOpponent 185 178 175 183 193 173 171 180 173 175 188 178
