The input and output screens are shown. The output screen provides the confidence interval (-1.782, .72155), the sample mean difference =-0.53, sample standard deviation = 2.26, and the sample size n = 15. Using the formula and Table IV : We have the sample mean difference =-0.53, the sample standard deviation = 2.26, and the sample size n = 15.

Apr 29, 2013 · He randomly selects records from 1100 such drivers in 2009 and determines the sample mean BAC to be 0.15 g/dL. with a standard deviation of 0.07 g/dL. Determine and interpret a 90% confidence interval for the mean BAC in fatal crashes in which the driver had a positive BAC. The 90% confidence interval for the mean BAC is (0.147, 0.153).

That is probably not an issue, as long as you name the test (two sample t interval) and list the d.f. that the calculator gave. Based on this sample, we are 99% confident that the true difference in the mean wait times (ambulance – self) of the population lies between -4.312 minutes and -2.076 minutes.
