Several years ago, 43% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,125 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,125 surveyed, 482 indicated that they were satisfied. Construct a 95% 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? Ho: P ▼ versus H1: p (Rour cimal places as needed.)

Leana is interested in the proportion of people who live in her area who own a dog. She randomly selects 50 addresses within a one-mile radius of her home and visits each to ask if they own at least one dog. Leana finds that 29 of the 50 homes she visited had at least one dog.

A high school counselor is interested in determining factors that contribute to high school drop out rates. One factor of interest to her is whether kids who are involved in team sports as children are less likely to drop out of high school. She surveys 41 high school graduates and finds that 30 were involved in team sports as children. She then surveys 38 high school dropouts and finds that 23 were involved in team sports as children. Construct and interpret a 90% confidence interval for the true difference between the proportions of high school graduates and dropouts who participated in team sports as children. Does this data suggest that there is a difference between these proportions at this level of confidence? Correctly round your results to the nearest tenth of a percent (one decimal place) in the intepretation of your interval.
