It is commonly said that 10% of people are left-handed, but Lilianna suspected that a higher proportion of art students at her university are left-handed. To test this theory, she took a sample of 150 art students and found
that p = 14% of the sample was left-handed.
To see how likely a sample like this was to happen by random chance alone, Lilianna performed a simulation. She
took a sample of n = 150 students from a population where 10% of the students were left-handed, and she
recorded what proportion of the sample was left-handed. She repeated this process for a total of 50 samples.
Here are the sample proportions from her 50 samples:
