Kathy sets out wanting to find a 98% confidence interval for a population mean; however, she later decides that she wants to know the 95% confidence interval for that same population mean. How will this affect the width and the margin of error of her confidence interval for a population mean? Assume that the population standard deviation is unknown and the population distribution is approximately normal.

Lisa decides that she wants to know the 85% confidence interval for a population mean despite originally setting out to find the 90% confidence interval. How will this affect the width and the margin of error of her confidence interval for a population mean? Assume that the population standard deviation is unknown and the population distribution is approximately normal. Select your answer from the choices below. The width will decrease, and the margin of error will increase. The width will...

a. Find a 98% confidence interval for the true mean of a population if a sample of 52 results in a mean of 100. Assume the population standard deviation is 12. b. Assume now that the same results occurred, the population was normal, and the sample size was reduced to 10. c. Repeat problem 2b assuming that the population standard deviation was unknown, and “s” was 12.

(1 point) Working backwards, Part I. A 90% confidence interval for a population mean is (44, 50). The population distribution is approximately normal and the population standard deviation is unknown. This confidence interval is based on a simple random sample of 28 observations. Calculate the sample mean, the margin of error, and the sample standard deviation. Use the t distribution in any calculations. Round non-integer results to 4 decimal places. Sample mean = Margin of error = Sample standard deviation...

Working backwards, Part I. A 90% confidence interval for a population mean is (82, 92). The population distribution is approximately normal and the population standard deviation is unknown. This confidence interval is based on a simple random sample of 24 observations. Calculate the sample mean, the margin of error, and the sample standard deviation. Use the t distribution in any calculations. Round non-integer results to 4 decimal places.

A student was asked to find a 98% confidence interval for widget width using data from a random sample of size n = 25. Which of the following is a correct interpretation of the interval 14.2 < μ < 24.4? Check all that are correct. There is a 98% chance that the mean of a sample of 25 widgets will be between 14.2 and 24.4. With 98% confidence, the mean width of all widgets is between 14.2 and 24.4. The...
