The contents of a random sample of 10 lubricant containers were recorded as follows: 10.2, 9.7, 10.1, 10.3, 10.1, 9.8, 9.9, 10.4, 10.3, and 9.8 liters. Assuming the distribution of the contents to be normal, is there a reason to believe that the true mean content of all lubricant containers is less than 11 liters?
