### Assessing Changes in Parental Satisfaction with K-12 Education QualitySeveral years ago, 44% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,095 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,095 surveyed, 471 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?**$ H_0 \colon p = \Box_1 $versus$ H_1 \colon p \neq \Box_2 $(Round to two decimal places as needed.)---**Options Provided on the Educational Website:**- Help me solve this- View an example- Get more help**Functions Available:**- Clear all- Check answer**Diagram/Graph Explanation:**In this segment, there are dropdown boxes for $ \Box_1 $ and $ \Box_2 $ which should be filled in with numerical values pertaining to the null and alternative hypotheses for the given statistical question. Additionally, the current time and weather (94°F, Mostly sunny) are displayed at the bottom right corner of the screen, along with the date (6/18/2022) and the notification for OneDrive being up to date.---This exercise guides you through constructing a 99% confidence interval and testing hypotheses related to changes in parental satisfaction with education quality over time. The snippet also provides interactive options for additional help and examples to aid in understanding.

In a survey, 14 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $34 and standard deviation of $11. Construct a confidence interval at a 80% confidence level.Give your answers to one decimal place.
A doctor claims that the mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night. To investigate, he selects a random sample of 50 high school seniors from all high schools in his county. He also selects a random sample of 50 seniors from the colleges in his county. He constructs a 95% confidence interval for the true mean difference in the number of hours of sleep for seniors in high school and seniors in college. The resulting interval is (0.57, 1.25). Based upon the interval, can the doctor conclude that mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night? yes because 1 is in the confidence interval yes because 0 is not in the confidence interval no because 1 is in the confidence interval no because 0 is not in the confidence interval
several years ago 42% of parents who had children in grades k-12 were satisified with the quality of education the students recieve. A recent poll asked 1,115 parents who have children in grades k-12 if they were satisfied with the quality of education the students recieve. Of the 1,115 surveyed 462 indicated that they were satisifed. Construct a 99% confidence interval to assess whether this represents evidence that parents attitudes towards the quality of education have changed. What is the upper and lower bound?
