Find the margin of error for the given values of c, s, and n.
c=0.9595, s=44, n=2828
The margin of error is ____. (Round to one decimal place as needed.)
pt. 2
Use the given confidence interval to find the margin of error and the sample mean.
(14.7, 21.7)
The sample mean is ____. (Type an integer or a decimal.)
pt. 3
In a random sample of 25 people, the mean commute time to work was 30.6 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean (muμ.)
What is the margin of error of muμ?
Interpret the results.
The confidence interval for the population mean muμ
is (__________)
