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 5 793.3 792.8 794.8 790.1 793.1 797.6 791.5 802.6 788.3 802.5 Click the icon to view the table of critical t-values. A B Determine the test statistic for this hypothesis test. to = = -1.42 (Round to two decimal places as needed.) Find the critical value(s) for this hypothesis test. 6 792.3 791.2 - 4.03,4.03 (Use a comma to separate answers as needed. Round to two decimal places as needed.) What is your conclusion regarding Ho? Do not reject Ho. There is not sufficient evidence at the x = 0.01 level of significance to conclude that there is a difference in the measurements of velocity between device A and device B. c) Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results. The confidence interval is (). (Round to two decimal places as needed.)
