A fair cube has a red face, blue face, green face, and a white face. During an experiment, the cube is tossed and the color it lands on is recorded. The cube lands on red 4 times as often as it lands on blue. The cube lands on blue twice as often as it lands on green. It lands on green as often as it lands on white.
A) CREATE and COMPLETE a PROBABILITY TABLE of FOUR COLORS.
B) DRAW a BAR GRAPH to represent the PROBABILITY DISTRIBUTION.

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.
