We have a gantry crane that handles one TEU container in 4 minutes. A new gantry crane developer claims that their machine handles one TEU container in 3 minutes. If this is statistically significant, we will purchase this new machine. We have selected 10 random container handling operation of this machine and tested their difference from the 4 minutes by ONE SAMPLE T TEST in the 5% confidence level. We have found T STAT as -3.323.What are the H0 and Ha for this question?Should we purchase this new machine or not? Why?
