You have a large vegetable garden that has beefsteak tomato plants. Bees account for close to 80% of pollination of fruits, vegetables, and seed crops. You want more bees to visit your garden because more pollination means more tomatoes. Research has shown that bees prefer flowers that are either yellow, white, or blue; however, they are not attracted to red flowers because they see red as an absence of color. You are curious to see if this is true. In your garden, you separate two environmentally similar spaces for your beefsteak tomato plants. In one of the areas, you add yellow flowers around the tomato plants; in the other area you add red flowers. A random sample of 15 tomato plants surrounded by yellow flowers was taken and the mean tomato yield weight was 12.4 pounds per plant with a standard deviation of 2.7. Another random sample of 16 tomato plants that were surrounded by red flowers showed a mean tomato yield weight of 11.5 pounds per plant with a standard deviation of 2.1. Is there a difference between the mean yield of the two groups? What are the critical values, the test statistic, the pvalue, the decision for this hypothesis test
