A recent poll of 1001 Americans age 18 and over conducted in May of 2013 found that 80% of the respondents “strongly agree” that K-12 schools should teach critical thinking to children. What is the sample size? For this survey, the margin of error is measured to be 3.2%. What is the 95% confidence interval using only 1 decimal?

Several years ago, 46% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,055 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,055 surveyed, 488 indicated that they were satisfied. Construct a 90% 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 (Type integers or decimals rounded to two decimal places as needed.) versus H,:p Use technology to find the 90% confidence interval. We are 90% confident the proportion of parents who had children in grades K-12 that were satisfied with the quality of education the students receive is between and (Type integers or decimals rounded to two decimal places as needed.) What is the correct conclusion? O A. Since the interval does not contain the proportion stated…

The 95% confidence interval for the mean contains the sample mean with 95% certainty.TrueFalse

Several years ago, 48% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,035 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,035 surveyed, 497 indicated that they were satisfied. Construct a 90% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. III What are the null and alternative hypotheses? Ho: P = 0.48 versus H₁: p 0.48 (Round to two decimal places as needed.) Use technology to find the 90% confidence interval. The lower bound is The upper bound is (Round to two decimal places as needed.) What is the correct conclusion? QA Since the interval contains the proportion stated in the null hypothesis, there is sufficient evidence that parents' attitudes toward the quality of education have changed. OB. Since the interval does not contain the…
