According to an article nearly 45% of all Americans have brown eyes. A random sample of 100 people found 32 with brown eyes. Is there sufficient evidence at 0.01 level to indicate that the proportion of brown-eyed people in the region where the study was performed differs from the value reported in the article? There is sufficient evidence to indicate that the proportion of brown-eyed people in the region where the study was performed differs from the value reported in the article (reject the null hypothesis). There is insufficient evidence to indicate that the proportion of brown-eyed people in the region where the study was performed differs from the value reported in the article (accept the null hypothesis).
