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.Observation1 2 3 4 5 6A 790.2 790.2 793.3 793.3 791.6 791.6 793.9 793.9 794.7 794.7 793.1 793.1B 794.8 794.8 789.0 789.0 796.2 796.2 793.5 793.5 802.9 802.9 791.3 791.3(a) Why are these matched-pairs data?A. All the measurements came from rounds fired from the same gun.B. Two measurements (A and B) are taken on the same round.C. The measurements (A and B) are taken by the same instrument.D. The same round was fired in every trial.(b) Is there a difference in the measurement of the muzzle velocity between device A and device B at thealpha equals 0.01α=0.01 level of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.Let diequals=Aiminus−Bi. Identify the null and alternative hypotheses.Upper H 0H0:mu Subscript dμdequals=00Upper H 1H1:mu Subscript dμdnot equals≠00Determine the test statistic for this hypothesis test.t0equals (Round to two decimal places as needed.)Find the P-value.P-valueequals=nothing(Round to three decimal places as needed.)
