A coworker claims that Skittles candy contains equal quantities of each color (purple, green, orange, yellow, and red). In other words, 1/5 of all Skittles are purple, 1/5 of all Skittles are green, etc. You, an avid consumer of Skittles, disagree with her claim. Test your coworker's claim at the α=0.01α=0.01 level of significance, using the data shown below from a random sample of 200 Skittles. Which would be correct hypotheses for this test? H0:H0: Red Skittles are cherry flavored;...

2. You carry out a dihybrid cross in sweet peas where you examine the flower color locus (use symbols based on "P" for this gene) and blooming time locus (use symbols based on "L" for this gene). You cross a true breeding purple- flowering, early blooming plant to a true breeding red-flowering, late blooming plant. The F1 plants are all purple- flowering and late blooming. The F1 plants were subsequently used in a testcross. The flower color locus and the...
