CBS News/New York Times poll used a convenience sample to survey 75 Americans and found that 61 people in the sample thought that it was a good idea to significantly cut taxes for small businesses in order to try and create jobs. Suppose you want to create a confidence interval for p, the true proportion of all Americans who thought it was a good idea to significantly cut taxes for small businesses in order to try and create jobs. Are all assumptions met to create this confidence interval?   Yes, both assumptions are met.   No, none of the assumptions are met.   No, only one assumption is met.   It is impossible to determine.

Several 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 1,075 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,075 surveyed, 479 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 = 0.44 versus H,: p 0.44 (Round to two decimal places as needed.) Use technology to find the 95% confidence interval. The lower is The upper bound is (Round to two decimal places as needed.)

According to a poll, 81% of California adults (410 out of 506 surveyed) feel that education is one of the top issues facing California. We wish to construct a 90% confidence interval for the true proportion of California adults who feel that education is one of the top issues facing California.What is a point estimate for the true population proportion?
