A Roper Starch survey asked employees ages 25 to 34 whether they would prefer better health insurance or a raise in salary. Of the 500 employees surveyed, 340 said they would prefer better health insurance. Using this sample information, develop a 98% confidence interval for the true proportion of employees who would prefer better health insurance.

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 1,135 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,135 surveyed, 474 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 versus H₁: p (Round to two decimal places as needed.) (…)

An online retailer has identified the maximum willingness of 10 consumers to pay for the same product. The 10 prices are: $10.00, $11.50, $9.50, $10.20, $11.20, $10.50, $9.80, $10.10, $9.90, $11.00 The retailer seeks a 95% confidence interval for the mean price consumers are willing to pay. The sample mean is calculated as $10.37, and the sample standard deviation is $0.66. Also consider the following t-values: Degrees of freedom 8 a. (9.99, 10.75) 9 10 90% confidence 1.86 1.833 1.812 95% confidence 2.306 2.262 2.228 99% confidence 3.355 3.250 3.169 Selecting the correct t-value, calculate the limits of the confidence interval.
