Of 120 business majors included in the survey, 20 said that they studied hard, as compared to 48 out of 150 nonbusiness majors who said that they studied hard. Use Table 1 Let pi represent the population proportion of business majors who study hard, and p2 the population proportion of non-business majors who study hard. Let business majors who study hard and non-business majors who study hard represent population 1 and population 2, respectively. a-1.

a-1. Option 2
a-2. Option 1
p1-population portion of business major = 20/120 = 0.167
p2-population portion of non-business major = 48/150 = 0.32
Since p1- p2 = 0.167-0.32 =-0.1533, there is enough evidence that portion of business majors who study hard is less than that of the non-business majors
