The data in the table below show the measurements of hemoglobin (g per 100 ml) in the blood of brown trout. The trout were placed at random in four different troughs. The fish food added to the troughs contained, respectively, 0, 5, 10, and 15 grams of sulfamerazine per 100 pounds of fish (coded A, B, C, and D). The measurements were made on 10 fish randomly selected from each trough after 35 days.

Create a summary plot of the data and comment b. Write down the null and alternative hypothesis for the test to see if there are any differences among the mean amounts of sulfamerazine added c. Test this hypothesis using an ANOVA and =0.05 and draw conclusions. d. Determine which means are different e. Draw conclusions to the real-world f. Did the outcome match what you thought would happen based on your plot, explain
