For given Exercise, find the Cp index. Comment on the ability of the process to meet specifications. What proportion of the specification range is used up by the process? If it is easier to change the process mean than to change its variability, to what value should the process mean be set to minimize the proportion of nonconforming product?
Exercise A pharmaceutical company producing vitamin capsules desires a proportion of calcium content between 40 and 55 ppm. A random sample of 20 capsules chosen from the output yields a sample mean calcium content of 44 ppm with a standard deviation of 3 ppm. Find the natural tolerance limits of the process. If the process is in control at the present values of its parameters, what proportion of the output will be nonconforming, assuming a normal distribution of the characteristic?
For following two regressions describe and interpret major parts from regression output. write down the difference between two regressions?
suppose you want to test the claim that mu!=3.5 with standard deviation unknown. Given a sample size of n = 40 and a level of significance of alpha=.05, when should you reject H0.

The estimated miles per gallon ratings of a class of automobiles are normally distributed with a mean of 12.8 and a standard deviation of 3.2. What is the probability that one of these automobiles selected at random would get:
The events A and B are independent, mutually exclusive or both. If two events A and B are mutually exclusive (A B = ), then they cannot be independent if P(A) > 0 and P(B) > 0. Why?
The mean of a normal distribution probability is 400 pounds. The standard deviation is 10. What is the area between 415 pounds and the mean of 400 pounds? (Round to 4 decimals)
How large a sample is needed to reduce the margin of error to at most 0.01 (or 1%)? Be conservative by not assuming the sample proportion (obtained from the sample of 500) as the reasonable guess for p. Use the confidence level you found in part (..
