Question

It is established by Mendelian theory that the predominant colors in the Waimea orchid (blue, red, violet, orange) will occur with the ratio of 7:5:5:3. When the first 75 Waimea orchid bulbs bloom, the predominant colors are 29 blue, 18 red, 22 violet, 6 orange. The florists are concerned that these bulbs are not Waimea orchids, but a similar appearing (and more common, less valuable) hybrid. Use Minitab to conduct an appropriate hypothesis test at = 0.05 to test this. Copy and paste all relevant test output into your paper. Interpret your results and state your conclusion in terms of the data and the question being studied.
