1) Neurological research has shown that in about 80% of people, language abilities reside in the brain's left side. Another 10% display right-brain language centers, and the remaining 10% have two-sided language
control. (The latter two groups consist of mainly left-handed people.)
Suppose a large class is split up into groups of 7 students. Use a simulation to determine the likelihood that
a randomly selected group has two students that either have right-brain or two-sided language control by
following the steps below.
a) For each trial, explain how many random numbers you will generate, the range of those random
numbers, and what the numbers represent. (For example, I will generate 4 numbers between 1 and 20
where 1-3 represent x, 4-7 represent y and 8-20 represent z.)
b) Write the calculator command you will use, along with the values, to generate each trial.
c) Create a table showing the components and outcome for 10 trials. An example of how to format your
table is below
Number of Students (that
Component have either right-brain or two
sided language control
(rive generated
numbers here)
(give newly generated
numbers here)
Continue to ble for 10 trials.
d) According to your simulation, what is the likelihood that a randomly selected group has two students
that either have right-brain or two-sided language control?
