A Vendor Was Interested in Determining Whether Two Soft Drink

Short Answer

A vendor was interested in determining whether two soft drink machines dispense the same amount of liquid. A sample of size seven was selected from each machine and the amount of liquid dispensed (in ounces) was recorded as Use the Wilcoxon rank sum test to determine whether the distributions for the amount of liquid dispensed are the same for both machines. Use = 0.05.
The null and alternate hypotheses are: : The distributions for the amount of liquid dispensed are identical for the two machines. : The distributions for the amount of liquid dispensed differ for the two machines.
What is the test statistic?
T:______________
What is the critical value for the test statistic?
______________
Thus: ______________
Conclude:
We conclude that the distributions of the amount of liquid dispensed by the two machines are ______________.
