(a) Is there a difference
in the measurement of the muzzle velocity between device A and
device B at the α = 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 di = Ai − Bi.
(i) Identify the null and alternative
hypotheses.
(ii) Determine the test statistic for
this hypothesis test (t0 = ?). Round to two

6. A shell is fired from a gun with a muzzle velocity of 20.0 m's, at an angle of 60.0 with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass. One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that the air drag is negligible? (You may use R-(v/g) sin(20) 7. In...
