You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 49 business days, the mean closing price of a certain stock was $113.41. Assume the population standard deviation is $11.13. a) The 90% confidence interval is (?) - (?)
You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 39 business days, the mean closing price of a certain stock was $113.67. Assume the population standard deviation is $10.91. The 90% confidence interval is (1 , b). (Round to two decimal places as needed.)

The population of Mosquito has an unknown mean lifespan μ with standard deviation σ = 0.55 days. A) A sample of 23 mosquito has a mean lifespan of 6.5 days. Construct a 87 % confidence interval to estimate the mean lifespan μ of the mosquito population. Round to 4 decimal places.) The interval: 6.5 (Round E to 2 decimal places) The interval in traditional format: ( B) For the same sample of 23 mosquito with mean lifespan of 6 5...
The days of training a new employee needs are normally distributed with a population standard deviation of 3 days and an unknown population mean. If a random sample of 23 new employees is taken and results in a sample mean of 18 days, use Excel to find a 90% confidence interval for the population mean. Round the final answer to two decimal places.
