The presence of mercury in fish is a health concern for people who eat them, especially forwomen who are or may become pregnant, nursing mothers, and young children. Thisproblem is concerned with mercury contaminant in Atlantic cod (Gadu morhua) caught atthe location of 68 12'0" N, 14°48'0" E, North Atlantic.There are three selected attributes, age, body length, and the output is the mercury level inthe fish muscle, as shown in Table 1. It is generally known that mercury concentrationincreases if age and/or body length increase.Table 1: Mercury concentration in different fish attributesb)c)No.1234567891011121314151617Age Body(Year) Length(cm)1819202222222232223422281323545044040045530440Divide fish into two groups:Group 1: Age 1-2,Group 2: Age 3-8.490450490435490460585500505435620430550MercuryConcentration(mg/kg)0.010.0110.0200.0200.0200.0200.0210.021Obtain the frequency distribution of the age in year.

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.

Can people tell the difference between a female nose and a male nose? This research question was examined in an article. Eight Caucasian males and eight Caucasian females posed for nose photos. The article states that none of the volunteers wore nose studs or had prominent nasal hair. Each person placed a black Lycra tube over his or her head in such a way that only the nose protruded through a hole in the material. Photos were then taken from three different angles: front view, three-quarter view, and profile. These photos were shown to a sample of undergraduate students. Each student in the sample was shown one of the nose photos and asked whether it was a photo of a male or a female. The response was then classified as either correct or incorrect. The following table was constructed using summary values reported in the article.
