Problem 2: 22 Points To test if Gabey liked all meals equally we ran an experiment. For 20 different nights we gave Gabey 4 different types of food and timed how long it took him to get to his bowl. Type Heart Liver Kidney Kibble No. Trials 5 5 5 5 Mean (seconds) 20 25 15 60 Std Dev (seconds) 5 6 7 10 (15pts) We can clearly see that Gabey takes, on average, different amounts of time to get to his bowl depending on the food type. Does this different look statistically significant? You can use a critical value of 3.25. (2pts) Clearly each food type has a different mean. How would we explain this if the result above is not statistically significant? (2pts) If we included all 3 of the organ groups together find the variance of those 15 times? (3pts) Is there significant evidence that organ meat gets him to the bowl quicker than kibble? (5pts) If Gabey is given heart 2 times and kidney once what is yuur 95% confi- dence interval for the total time of 3 trips to the bowl.
