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 191 182 179 183 200 174 Height (cm)of Main Opponent 183 185 178 181 184 176 a. Use the sample data with a 0.01significance 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? Identify the test statistic. t= Identify the P-value. P-value = What is the conclusion based…
CHAPTER EXERCISES C1. Suppose you surveyed 30 people and asked them whether they are white (W) or nonwhite (N) and how many traumas (serious accidents, rapes, or crimes) they have experienced in the past year. You also asked them to tell you whether they perceive themselves as being in the upper, middle, working, or lower class. Your survey resulted il the raw data presented in the following table: a. Identify the level of measurement for each variable.
