Question 1151772: The following random sample was selected : 4, 6, 3, 5, 9, 3. Find the 95% confidence interval for the mean of the population. See Ex. 2 (Use your graphing calculator to find the mean and sample standard deviation.) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! mean is 5
sd is 2.28
95% CI half-interval is t df=5, 0975=2.571*s/sqrt(n)=2.39; s=2.28 and n=6
95% CI is (5-2.39, 5+2.39) or (2.61, 7.39)
