Darts A student interested in improving her dart-throwingtechnique designs an experiment to test 4 differentstances to see whether they affect her accuracy. Afterwarming up for several minutes, she randomizes theorder of the 4 stances, throws a dart at a target using each stance, and measures the distance of the dart in centime-ters from the center of the bull’s-eye. She replicates this procedure 10 times. After analyzing the data she reportsthat the F-ratio is 1.41.a) What are the null and alternative hypotheses?b) How many degrees of freedom does the treatmentsum of squares have?

Weight Gain of Athletes A researcher wishes to see whether there is any difference in the weight gains of athletes following one of three special diets. Athletes are randomly assigned to three groups and placed on the diet for 6 weeks. The weight gains (in pounds) are shown here. At a=0.005, can the researcher conclude that there is a difference in the diets? Diet A: 3, 4, 5, 6 Diet B: 12, 13, 14, 6, 7, 8 Diet C: 3, 4, 5 ,6 Part 2. State the hypotheses and identify the claim with the correct hypothesis. Part 3. Compute the test value. Always round score values to two decimal places. Part 4. Find the -value.
