A soda bottling company knows the fill volumes of their 16 ounces bottles is approximately normally distributed. A sample of 10 bottles is obtained an their fill volumes are shown below:
15.0, 16.3, 16.1, 15.5, 15.8, 16.0, 15.3, 16.2, 15.4, 15.1
Is there reason to believe that the population average of 16 ounces soda bottles is less than 16.0 ounces? /Use alpha = 0.02 to test the hypothesis.
