Twenty patients sampled at random were matched by ageand BMI. One of each pair was assigned at random to a new treatment and the other toan existing treatment. Ultrasound examination of a certain tumour weight (in grams)produced the following results.Existing Treatment 15.58.5 10.6 12.5 6.5 8.4 10.5 87 7.510New Treatment145.7 9 11.5 1089.9 10.5Test whether there is a difference in the two treatments at 5% level of significance.

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.
