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 A 794.5 792.7 792.1 790.4 791.9 7915 B 797.1 792.1 798.0 786.6 800.5 786.7 Is there a difference in the measurement of the muzzle velocity between device A and device B at the alpha equals 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 d Subscript iequalsA Subscript iminusB Subscript I. Identify the null and alternative hypotheses. Upper H O: mu Subscript d equals 0 Upper H 1: mu Subscript d not equals 0 Part 3 Determine the test statistic for this hypothesis test. + Subscript Oequals enter your response here (Round to two decimal places as needed.)
