Question 1158550: Suppose you record the time spent for lunch for seven days and the results are: 10, 13, 15, 13, 16, 21, and 18 minutes. If the population (all days) is normally distributed, construct a 98% confidence interval for the population mean. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 98%CI is mean +/-t(0.99, df=6)*s/sqrt(n)
15.14 is mean, s=3.63, n=7
t=3.143
interval half width is 4.31 (margin of error)
(10.83, 19.45)
