Three students, Linda, Tuan, and Javier, are given laboratory rats for a nutritional experiment. Each rat's weight is recorded in grams. Linda feeds her rats Formula A, Tuan feeds his rats Formula B, and Javier feeds his rats Formula C. At the end of a specified time period, each rat is weighed again, and the net gain in grams is recorded.

At the end of a specified time period, each rat is weighed again, and the net gain in grams is recorded. Formula A 47 50 42 20 21 46 60 19 56 Formula B Formula C 27 36 33 33 38 59 51 48 19 25 22 36 25 30 58 Assume that all distributions are normal, the three population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of a = 0.1. Ho: μ1 = μ₂ = μ3 H₁: At least two of the means differ from each other. 1. For this study, we should use Select an answer ✓ 2. The test-statistic for this data = (Please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) 3. The p-value for this sample= 4. The p-value is Select an answer 5. Base on this, we should Select an answer 6. As such, the final conclusion is that... a hypothesis There is insufficient evidence to support the claim that nutritional formula type is a factor in weight gain for rats. There is sufficient evidence to support the claim that nutritional formula type is a factor in weight gain for rats.
