Which is an INCORRECT way to analyze the process capability of a process (on a particular quality characteristic) that is not normally distributed? a. Use Cp(q) b. None of those listed c. Transform the data to normal first and use the transformed data on indices such as Cp which work well on normally distributed data. d. Use Cpc e. Use Cpmk

What are control values that are far from the main set of values. ______occurs when the data set can be accurately described by the SD and the mean , when the data elements are centered around the mean and focuses on the distribution of errors Defined as the number of independent data points from the mean. Is present in all measurements. due to instrument, operator and environmental conditions (ex. pipetting error, mislabelling, temperature flocculation, improper mixing of sample and reagents). Highest frequency of clerical errors occur with the use of handwritten labels and request forms. Most widely used chart. Is a graphic representation of the acceptable limits of variation.

(CO 3) The soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. The company takes readings of every 10th bar off the production line. The reading points are 5.8, 5.9, 4.9, 5.2, 5.0, 4.9, 6.2, 5.1, 6.7, 6.1. Is the process in control or out of control and why? Group of answer choices It is out of control as one of these data points is more than 3 standard deviations from the mean It is in control as the data points more than 2 standard deviations from the mean are far apart It is in control as the values jump above and below the mean It is out of control as two of these data points are more than 2 standard deviations from the mean
Statistical process control (SPC) is a quality-control technique that primarily involves using statistics _____. A. To monitor production quality during the production process B.

Please do not give solution in image formate thanku. The specification for a plastic liner for concrete highway projects calls for a thickness of 6.0 mm ± 0.1 mm. The standard deviation of the process is estimated to be 0.02 mm. The process is known to operate at a mean thickness of 6.03 mm. What is the Cp and Cpk for this process? Determine whether this process meet 3-sigma requirements, 6-sigma requirements, or doesn’t meet any requirements.
In each of the following situations, indicate whether a fixed (F), sequential (S), or discovery (D) attributes sampling plan is being used. The audit team has determined the tolerable rate of deviation to be 5%, the risk of overreliance to be 10%, and the expected population deviation rate to be zero. The audit team is performing a sampling application to evaluate the operating effectiveness of an entity’s internal controls. The application used could provide a more efficient method of examination, but it is important that the audit team evaluate the sample in the order they were selected. The audit team established the risk of overreliance to be 5%, the tolerable rate of deviation to be 4%, and the expected population deviation rate to be 3%. Using the AICPA Sample Size tables, the audit team decided to sample over 1,000 items. Using the AICPA Sample Size tables, the audit team determined the appropriate sample size and selected the sample items. However,…
Which of the following statements is NOT true about the process capability ratio? a. The process capability ratio is a ratio for determining whether a process meets design specifications. b. The process capability ratio is computed as the difference of the upper and lower specification limits divided by six standard deviations. c. The process capability ratio is a ratio of the specification to the process variation. d. A capable process has a process capability ratio less than one.
