Question

001 0&quiz-action; = takeQuz&quiz-probGuid-QNAPC0A801; 01 0000003bd55cc0080000&ckzn.15; 1 2 438827555 0AAA6B04015E6ES S. Sample data, sample size, the confidence level, and the confidence interval Aa Aa 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 is known. You and your teammate work with the same sample. Your teammate chooses a larger 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 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 O They are centered at the same value. O They are centered at different values. Being as specific as you can, which of the following statements best describes the widths of the two intervals? O Your teammate's interval is narrower than yours. O They are the same width Your teammate's interval is wider than yours. O They are not the same width.

Explanation / Answer

a) They are centred at same values, because sample mean will be same

b) Your teammate interval is wider than yours, because he's chooses a larger interval than us, so precision will be low in Teammate Interval and thus it will be wider. Option C is Correct
