You are a member of a team studying the automobile industry. One phase of your investigation is to develop an interval estimate of the average distance that automobile-parts suppliers are located from Detroit. The population standard deviation o is unknown. You and your teammate work with the same sample. Your teammate chooses a smaller confidence level than yours. Think about plotting both your interval estimate and your teammate's interval estimate on a number line and then comparing where they sit and their widths. Being as specific as you can, which of the following statements best describes where the intervals sit on the number line? O They are centered at different values. O Your teammate's interval is centered at a lower value than yours. O Your teammate's interval is centered at a higher value than yours
