I assume the valve can fail to meet specification by producing a pressure that is either to big or too small. Therefore, the research (or alternative) hypothesis is that the valve has a pressure not equal to 4.5. The null hypothesis is that the valve pressure is equal to 4.5. Symbolically, Ho: pressure = 4.5 and Ha: pressure != 4.5.
