An industrial cooking process requires that one of its inputs contains a mix of precisely 50% of two different ingredients. The factory uses 4 different instruments to measure the contents of the input before it enters production. Each instrument is known to give results which follow a normal distribution, and have a standard deviation of 0.15% either side of the true value. Suppose that the mean value across the four instruments is 49.8%, and you wish to conduct a hypothesis test (with a significance level of 5%) to see whether the mix is significantly different from 50%. 1.What is the standard error? 2. What is the critical value? 3. What is the sample value?
