Example #1 As part of an experiment to determine how different types of soll cover would affect tomato plant production, groups of 3 plants each were subject to varying soil cover conditions. All plants grew under the same conditions except for the varying soll cover conditions and the weight of the tomatoes in grams is summarize. Assume that all the criteria for ANOVA hypothesis are met.
