State the null and alternative hypotheses. A chip manufacturer purchases silicon wafers (discs) which are used to build the circuits of certain microprocessors. The mean diameter of the wafers is supposed to be 5.1 centimetres with a standard deviation of 0.13 cm. If the wafer is too small or too large, it will damage the equipment used to manufacture microchips.The manufacturer measures the diameter in a sample of 17 wafers to establish if the mean diameter significantly departs from the required size. The sample produced an average diameter of 5.23 cm.
