Pocket
6 in
you are told that in a billiards shot, the cue ball was
shot at the eight ball, which was 8 inches away. as a
result, the eight ball rolled into a pocket which was 6
inches away
knowing that the angle made with the path of the cue
ball and the resulting path of the eight ball is larger
than 90°, it can be determined that the original distance
from the cue ball to the pocket was greater than
inches

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
