The specification for a pump is that the flow rate be more than 5 gallons per minute (gpm). In an initial study, eight runs were made. The average flow rate was 6.5 gpm and the standard deviation was 1.9 gpm. If the mean flow rate is found to meet the specification, the pump will be put into service. Assume that the pump only has an average flow rate of 4.7 gpm. The pump is put into service. Is this a Type I error, Type II error, or the correct decision
