Question 862644: Find the Confidence Interval Specified
Physiologist often use the word forced vital capacity as a way to assess a person's ability to move air in and out of their lungs. A researcher wishes to estimate the forced vital capacity of people suffering from asthma. A random sample of 15 asthmatics yields the following data on forced vital capacity, in liters.
4.8, 4.3, 3.2, 3.1, 3.7, 3.5, 4.2, 4.3, 4.8, 3.0, 3.5, 4,0, 3.4, 5.2, 5.1
Use the data to obtain a 95.44% confidence interval for the mean forced vital capacity for all asthmatics. Assume that SD=.6

Hi

ME = 1.5891(6)/sqrt(15) = 2.46

CI: mean-ME < u <  mean + ME

find Your Sample mean (sum/16) and use ME given to calculate CI
