The fоllоwing dаtа represent the muzzle velоcity (in feet per second) of rounds fired from а 155-mm gun. For each round, two measurements of the velocity were recorded using two different measuring devices, resulting in the following data. Observation 1 2 3 4 5 6 A 790.9 784.2 791.4 790.8 795.5 789.3 B 799.8 790.1 795.9 796.7 791.6 794.8 a) Is there a difference in the measurement of the muzzle velocity between device B and device A at the α=0.10 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 di=Ai−Bi. Identify the null and alternative hypotheses. H0:
