To investigate the relation between hair color and eye color,
the hair color and eye color of 5383 persons
was recorded. The data are given in the following table:
Hair Color
Eye Color | Fair/red Medium Dark/black
Light | 1168 825 305
Dark | 573 1312 1200
Eye color is encoded by the values 1 (Light), and 2 (Dark), and
hair color by 1 (Fair/red), 2 (Medium),
and 3 (Dark/black). By dividing the numbers in the table by 5383
(the...
20 people's hair color was observed and was coded as follows:
Blond=1; Brown=2; Red=3; Blue=4
1,2,2,1,3,2,2,1,2,4,2,2,3,3,1,2,1,4,2,2...

a) Draw the graph that best illustrates this data
b) For the above data which is the best measure of central
tendency? Calculate it and explain why it is the best to use inthis
situation

1.) Suppose that for any child in a particular family, black
hair, blonde hair, red hair, and green hair are all equally likely.
If this family has two children, what is the probability that the
kids will have the same hair color?
2.) Suppose that in a different family, the probability of a
child having black hair is .45, the probability of a child having
blonde hair is .3, the probability of a child having red hair is
.1, and...

the region to the right, make an appropriately labeled frequency
table in regard ONLY to the hair color data (for this portion,
ignore all other variables in the data set except hair
color). Next, extend the frequency table to include a
relative frequency column. Finally, create a bar chart
graphic from the frequency table.
