A researcher studied the time between initial submission and publication of articles in two journals. For
254254
articles published in journal A, the mean length of time was
2424
months, with a standard deviation of
66
months. For
224224
articles published in journal B the mean length of time was
3030
months, with a standard deviation of
1515
months. Create a90% confidence interval for the difference in mean delay,
mu Subscript Upper B Baseline minus mu Subscript Upper AμB−μA.
Do not assume that the variances are equal.
The confidence interval is left parenthesis nothing comma nothing right parenthesis .,.
(Round to two decimal places as needed.)

To construct a confidence interval for the difference between two population means mu 1 minus mu 2, use the formula shown below when both population standard deviations are known, and either both populations are normally distributed or both n 1 greater than or equals 30 and n 2 greater than or equals 30. Also, the samples must be randomly selected and independent. left parenthesis x overbar 1 minus x overbar 2 right parenthesis minus z Subscript c Baseline StartRoot StartFraction...

In a random sample of 25 people, the mean commute time to work was 30.2 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 80% confidence interval for the population mean mu. What is the margin of error of mu? Interpret the results. The confidence interval for the population mean mu is left parenthesis nothing comma nothing right parenthesis . (Round to one decimal place as needed.) The...

A manager wants to compare the mean time required to build a product using two different assembly methods, A and B. The time per unit was recorded for independent random samples from each method. The results are below. Assuming that the variances for the two populations are equal, use this data to form a 99% confidence interval for the true difference (μA−μB)(μA−μB) between the mean times for the two methods. Do not round intermediate calculations. Enter your final answers as...
