A sociologist tests whether this percentage is different today by conducting a random sample of 400 females aged 15 years of age and older and finds that 216 are living alone. Is there sufficient evidence at the o = 0.01 level of significance to conclude the proportion has changed? Identify the null and alternative hypotheses for this test. O A. Ho: p > 0.53 B.

A recent poll asked 1, 165 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1, 165 surveyed, 477 indicated that they were satisfied. Construct a 99% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. What are the null and alternative hypotheses?
