Over the year, the Mars company has changed both the colors and the proportion of colors for M&M candies. The original colors were red, yellow, violet, green and brown. In 1995 blue was introduced. Mars actually published the proportion of colors in 1997 and 2008 (see chart below). One day, all the color proportion data disappeared, and it has since been a mystery. Your job is to compare the color proportions of today's M&Ms to the 1997 and 2008 data to figure out what (if anything) has changed. 1997 2008 35% 30% 30% 30% 25% 24% 25% 20% 20% 20% 15% 20% 14% 15% 13% 13% 10% 10% 10% 10% 20% 16% 10% 5% 5% 0% 0% Browm Yellow Red Orange Green Blue Brown Yellow Red Orange Groen Blup Conduct a 1-sample hypotheses test of proportions to test the following claims: The proportion of yellow M&Ms today is greater than the proportion of yellow M&Ms from 1997. At a 0.10, is there enough evidence to support the claim? (Use p-values) Step One: H and H The proportion of blue M&Ms today is equal to the proportion of blue M&Ms from 2008. At a = 0.01, is there enough evidence to support the claim? (Use critical values) Step One: H and H Step Two: a Step Three: Test Dist. Step Four: Decision rule Step Two: a Step Three: Test Dist. Step Four: Decision rule Step Five: Calculate and Interpret Step Five: Calculate and Interpret Step One: H and H Step Two: a Step Three: Test Dist.
