MATH 2311 Section 8.4
Comparing Two Proportions When comparing two population proportions in an inference test, we use a two-sample z test for the proportions. The null and alternate hypotheses would be:
Example: Is the proportion of left-handed students higher in honors classes than in academic classes? Two hundred academic and one hundred honors students from grades 6-12 were selected throughout a school district and their left or right handedness was recorded. The sample information is: Is there sufficient evidence at the 5% significance level to conclude that the proportion of left-handed students is greater in honors classes?
