Quiz 2 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 = 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: I-I-I-l-H-l-I-I-l-I-I-l-H-l-I-I-l 0.04 0.06 0.08 0.1 0.12 0.14 0.16 Simulated sample proportions 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 pvalue of the test? Note: The sample result was 13 = 14%. She wants to test H0 :1) = 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 13 = 14%.
