Question

It is known that the yield of a chemical process is normally distributed with mean of 12 g/Kg and variance of 4.2(g/kg)$^2$. g) Specify the value of the yield that is 2 standard deviations above the mean. [10 points] h) Determine specifications that are symmetric about the mean and include 85% of all yields. [10 points] i) Industry standards require that the yield should be more than 8 g/Kg in 95% of the cases. Check if the particular chemical process meets the requirement. [10 points]
