Wild irises are beautiful flowers found throughout the United States, Canada, and northern Europe. This problem concerns the length of the sepal (leaf-like part covering the flower) of different species of wild iris. Data are based on information taken from an article by R. A. Fisher in Annals of Eugenics (Vol. 7, part 2, pp. 179 -188). Measurements of sepal length in centimeters from random samples of Iris setosa (I), Iris versicolor (II), and Iris virginica (III) are as follows below. I II III 5.9 5.8 6.9 4.8 6.5 5.6 4.6 6.4 4.9 5.7 4.3 7.7 4.8 5.8 5.6 5.4 6.3 6.3 5.8 5.5 6.6 Shall we reject or not reject the claim that there are no differences among the population means of sepal length for the different species of iris? Use a 5% level of significance. (b) Find SSTOT, SSBET, and SSW and check that SSTOT = SSBET + SSW. (Use 3 decimal places.) SSTOT = SSBET = SSW = Find d.f.BET, d.f.W, MSBET, and MSW. (Use 4 decimal places for MSBET, and…
Twenty sculptors were asked to produce molds of a model using a different medium for each one. The options are: having the model present at the session, using a photograph and seeing the model, but having to create the sculpture from memory. The sculptor then rated the difficulty of creating each piece of artwork (1=easy; 10 = difficult). The data is provided below: Subject Model Present Photo Memory 1 9 5 5 2 3 9 6 3 6 8 9 4 1 6 10 5 5 7 7 6 9 4 1 7 8 8 10 8 6 9 4 9 8 3 8 10 1 8 10 11 8 5 10 12 8 7 5 13 6 10 3 14 9 2 7 15 5 8 9 16 1 6 8 17 7 4 7 18 10 9 1 19 3 6 10 20 10 10 10 1.

A study measures the absorption rate of three different types of organic chemical solvents. These solvents are used to clean industrial fabricated-metal parts and are potentially hazardous. The organic chemical solvents are Aromatics, Chloroalkanes and Esters. Aromatics ChloroalkanEsters es 0.95 1.58 0.43 1.15 0.91 0.61 0.82 0.83 0.34 1.05 1.16 0.60 0.57 0.53 1.45 Test if there is a significance difference in the mean absorption rate for the three solvents? Use a = 0.05.
