Hosmer winery on Cayuga Lake, New York has the machine for dispensing their wine into bottles, which are advertised to contain 750 ml. When the machine is in statistical control, the amount dispensed has a mean of 752 ml. Four observations are taken each day, to plot a daily mean over time on a control chart to check for irregularities. The most recent day's observations were: 745, 740, 750, 745. Could the difference between the sample mean and the target value be due to random variation, or can you conclude that the true mean is now different from 752? Answer by showing the five steps of a significance test, making a decision using a .05 significance level.
