Is (B) correct on 'How do the control limits change' ? please explain The overall average on a process you are attempting to monitor is 55.0 units. The process population standard deviation is 1.84. Sample size is given to be 4.a) Determine the 3-sigma x-chart control limits.Upper Control Limit (UCL;) = 57.76 units (round your response to two decimal places).Lower Control Limit (LCL-) = 52.24 units (round your response to two decimal places).b) Now determine the 2-sigma x-chart control limits.Upper Control Limit (UCL;) = 56.84 units (round your response to two decimal places).Lower Control Limit (LCL-) = 53.16 units (round your response to two decimal places).How do the control limits change?A. The control limits for the 2-sigma x-chart and for the 3-sigma x-chart are the same.B. The control limits are tighter for the 2-sigma x-chart than for the 3-sigma x-chart.C. The control limits are tighter for the 3-sigma x-chart than for the 2-sigma X-chart.

The x-chart is one of the control chart which is used to analyses the process variability (in terms…

ALREADY HAVE FIRST THREE ANSWERS NEED THE REST. ANOVA. Dr. Milgram is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results. Group 1) “Like a lot” Mean: 8 SS: 2 N: df: Group 2) “Like somewhat” Mean: 5 SS: 6 N: df: Group 3) “Dislike a lot” Mean: 2 SS: 4 N: df: Grand Mean: 4 df Within-Group: 9 df Between-Groups: 2 Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22)…

Set up the appropriate control charts for the 30 days of data. Calculate the control limits for each chart. Plot the data for the 30 days in an Xbar chart and an R chart. Using on the data file provided in the previous step, set up the appropriate control charts for the 30 days of data, calculating the control limits for each chart. What is the upper control limit for the X-bar Chart? Enter your response to three decimal places. You do not need to include the units (minutes), ONLY the numeric value. USE EXCELL DATA

A warden is motivated to reduce to aggressive interactions between inmates that sometimes occur in common areas like the yard. He tasks you, the prison psychologist, to find out what can be done to reduce aggressive behavior. Having known the prisoners, you hypothesize that there must be a relation between aggressiveness and having something to keep oneself busy. You get 10 volunteer inmates and give them a scale of aggression and then ask how many hours a week on average they spend with a hobby.The data in z-scoresare: C. Your spouse is a teacher at a highschool. You convince them to run the same scales on some of their students and the r value is .42. At ?=.01is that significantly different than for the one for the inmates?
