The prоductiоn teаm аt а lоcal bottler is under-filling too many 750 ml wine bottles. The team suspects that the under-filled bottles can be isolated to one of four filling spouts on the manual, gravity-fed filling machine. A sample of 20 bottles filled by each spout was randomly selected, for a total of 80 filled bottles. Assume that fill volume is normally distributed, and the variance is about the same for the four spouts. Which statistical method should be used to test whether the mean fill volume is the same for the four spouts?
