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…
Several years ago, 35% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,195 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,195 surveyed, 483 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?

What do the results tell about the mean attractiveness ratings of the population of all adult females? 7, 7, 3, 8, 5, 6, 6, 9, 8, 10, 4, 9 What is the confidence interval for the population mean u? __ < u < __ (Round up to one decimal place as needed)
I sampled 10 downtown Chicago restaurants for the price of their most expensive meal on the menu. Here are the prices: $45, $80, $70, $70, $60, $65, $80, $60, $50, $90 Construct a 99% confidence interval for the mean price of the most expensive meal at a downtown Chicago restaurant. Assume the population is approximately normal. Write a sentence using that confidence interval Using the values in the previous question, compute a 95% confidence interval for the standard deviation of the most expensive price for a mean in downtown Chicago.
