## Answer to relevant Questions

The surface tension of a chemical product, measured on a coded scale, is given by the relationship (3 + 0.05x)2 x where x is a component of the product with probability distribution Find the mean and variance of s. A sample of ten items from a normal population had a mean of 300 and standard deviation of 10. Using these data, estimate a value for the random variable such that the probability is 0.95 that 90% of the measurements on this ...Consider the hole diameter data in Exercise 6.9. Estimate process capability using x and R charts. If specifications are 0 ± 0.01, calculate Cp, Cpk, and Cpkm. Interpret these ratios.
