An experiment was done to study how different sandwich fillings might affect the mean number attracted to pieces of a sandwich the students running this experiment also varied the type of bread for the sandwiches randomizing between four types: Multigrain, Rye, Wholemeal, and White. The ant counts in 6 trials and summary statistics for each type of bread and the 24 trials as a whole are given in Table 1 and stored in SandwichAnts. a. use the summary information to compute the three sums of squares needed for using ANOVA to test for a difference in mean number of ants among four types of bread. Round your answers to one decimal place. SGG: SSE:

b. Use the sums of squares from part ( a) to construct the NOVA table and complete the details for this test. Fill in the following ANOVA table. Enter exact answers for degree of freedom, round your answer for the F-statistic to two decimals places, and round all other answers to one decimal place. What is the p- value? Round your answer to three decimal places.
What is the conclusion of the test?
Is there evidence of a difference in a mean number of ants based on bread type?
