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:

She wants to test H0:p=10% vs. Ha:p>10% where p is the proportion of art students at her university who are left-handed.

Based on these simulated results, what is the approximate p-value of the test?
Note: The sample result was p^=14%.
