For PART B USE A TI 84 AND LIST THE STEPS THAT YOU DID! THANK YOU
Researchers want to determine whether all bags of Skittles® have the same proportion of colors regardless of the flavor of Skittles®. To test this, they randomly sampled king-size bags of each flavor and recorded their findings in the table.
Flavor | Skittles® Color | ||||
---|---|---|---|---|---|
Red | Orange | Yellow | Blue | Green | |
Original | 15 | 20 | 18 | 12 | 16 |
Tropical | 10 | 7 | 9 | 18 | 5 |
Wild Berry | 16 | 12 | 13 | 8 | 10 |
Part A: What are the correct degrees of freedom
for this table? (2 points)
Part B: Calculate the expected count for the
number of blue tropical Skittles®. Show your work. (3 points)
Part C: Is there sufficient evidence that there is
a difference in the proportion of colors for the different flavors
of Skittles®? Provide a statistical justification for your
conclusion. (5 points)
