Please answer those multiple choice questions. Thank you.

a) After analyzing twenty samples of five observations each, a process is said to be in statistical control. A summary of the data set is as follows: 2. x:= 3970 and 2,6%,- x)2 -1.5 n-1 You are interested in knowing if the process is capable of producing an output within 2007. Assume that the quality characteristic is normally distributed when answering this and the next two questions What is the most appropriate capability ratio for this case? a. (1/Cp) b. Cpk Either the Cp or the pk b) What is the most nearly value of the most appropriate capability ratio? a. 1.55 6.0.63 c 1.88 d. 1.22 c) Based on the results, is the process capable of producing output within specifications? a. Yes, because the capability ratio is greater than 1.33 b. No, because the capability ratio is less than 1.33 c. No, because the capability ratio is greater than 1.33 d. Yes, because the capability ratio is less than 1.33 d) The one-sided process capability ration (Cpk) is misleading if: 1. The process is not stable. ii. The process output is not normally distributed. iii. The process is not centered. Select one: a. i and iii b. ii and ili c. i and if d. i, ii, and it e) Pareto charts are used for identifying a. The most important types of issues b. The relationship between two variables C. The most frequent types of issues d. The shape of a distribution f) This tool depicts the distribution and spread of process data a. Pareto charts b. Histograms C. Value stream maps d. Process flow charts
