The shop floor manager in a dairy company believes that the milk packaging process unit for one-liter packs is not working fine (the quantity of milk is not 1 liter in all the packages) and needs calibration. The manager wants to validate whether the average quantity of milk in a one-liter pack is different from 1 liter. He frames the null hypothesis as

LaTeX: H_0: \mu = 1, where LaTeX: \mu is the mean quantity of milk in one-liter packs.

What would be the alternative hypothesis to test that the mean quantity is different from 1 liter?
