You can put this solution on YOUR website! A random sample of six cars from a particular model year had the following fuel consumption figures (in miles per gallon). Find the 80% confidence interval for the true mean fuel consumption for cars of this model year.
Sample Data- 18.8,18.2,20.5,19.5,18,20.5
-----
x-bar = sum/6 = 19.25
std = 1.1
ME = 1.28*1.1 = 1.41
-----------------------
Left Endpoint = 19.25-1.41
Right Endpoint = 19.25+1.41
------------------
