The following data represent the muzzle velocity (in feet per second) of rounds fired from a 155-mm gun. For each round, two measurements of the velocity were recorded using two different measuring devices, resulting in the following data, Complete parts (a) through (d) below. Observation 1 2 3 4 5 6 5 A 791.2 792.9 7947 794.8 791.6 793.3 R 795.3 789.6 795.4 792.0 798.8 790.5 Interpret the confidence interval. Choose the correct answer below. O A. One can be 99% confident that the mean difference in measurement is 0. O B. One can be 99% confident that the mean difference in measurement is 0.01. O C. One can be 1% confident that the mean difference in measurement lies in the interval found above. O D. One can be 99% confident that the mean difference in measurement lies in the interval found above d) Draw a boxplot of the differenced data, Does this visual evidence support the results obtained in part (b)? O A. O B. 8 6 4 2 0 2 4 6 4 2 0 2 4 Differences Differences OC O D 8 6 4 2 0 2 4 0 8 8 4 2 0 2 Differences Differences Does this visual evidence support the results obtained in part (b)? O A. Yes, because the boxplot shows no outliers O B. No, because the boxplot is too large. O C. . No, because 0 is not contained in the boxplot. O D. Yes, because 0 is contained in the boxplot.
