Use the following information for the question. A group of home gardeners want to test whether the type of soil used to grow heirloom tomatoes has an effect on the number of tomatoes harvested. Gardeners randomly assigned tomato plants to be grown in soil with no fertilizer, commercial plant food, and homemade compost. All other growing conditions were kept the same. Forty plants were assigned to each group. At the end of the growing season the number of tomatoes harvested was counted. Assume that all other conditions for the ANOVA test have been met. One-way ANOVA F=0.762135 P=0.5202354 Factor df-2 SS=710.349206 MS=355.174603 Using the test results provided, test the hypothesis that soil treatment affects the number of tomatoes harvested.

The kindergartners and first and second graders were talking about their favorite field trips during the school year. One of the teachers, Ms. Brewer, turned the discussion into a math lesson, and the students conducted a survey. Each child wrote down on paper which trip was his or her favorite. (Note that many children named more than one field trip as their favorite.) The survey revealed that 55 wrote down the trip to the river, 48 indicated the trip to the police station, and 38 included the trip to the hardware store. The police station and the river were chosen on 32 papers, 26 papers included both the river and the hardware store, and 22 children wrote down the police station and the hardware store on their papers. Ms. Burke counted 17 papers that included all three and one that did not list any of the three trips. How many children were surveyed? How many children wrote down the river but not the police station? How many children did not list the hardware store?
