4) Now that Continental can detect more defects before the Silver Box is shipped, I decided process Improvements in its circuit board fabrication department would further improve quality. So, for one process they collected the following data this morning to set up a mean control chart. Since the process mean is unknown, estimate the mean and find the UCL and LCL for a 3-sigma mean control chart using this morning's samples. Sample 1 - 24, 24, 25, 22, 21 Sample...
Can you please help solve and explain this...Thanks The Mini Mental State Examination (MMSE) is a commonly used test for diagnosing memory impairment in adults. This test is sometimes used in clinical settings as a part of the process for diagnosing dementia. A person’s cognitive status is determined by comparing his or her raw score with the descriptive statistics of a norm group of test takers of similar ages and educational levels. Imagine that you had administered the MMSE to...
Question #5: A statistics teacher wants to see whether there is a statistically significant difference in the ages of day students and night students. A random sample of 31 students is selected from each group. The data are given below. Test the claim that there is difference in the mean ages of the two groups. Use a 0.01 Day Students: 22 24 24 23 19 19 23 22 18 21 21 18 18 25 29 24 23 22 22 21...
The data in the table below represent individual observations on molecular weight taken hourly from a chemical process. The target value of molecular weight is 1050 and the process standard deviation is thought to be about ? = 25. Please use software outputs to present your analysis. (a) Set up a tabular CUSUM for the mean of this process (choose appropriate ? and ℎ). (b) Set up an EWMA control chart with appropriate ? and ?. Observation Number 1 2...
17. (10points) One hundred product labels are inspected every day for surface nonconformities. Results for the past 25 days are 22, 29, 25, 17, 20, 16, 34, 11, 31, 29, 15, 10, 33, 23, 27, 15, 17, 17, 19, 22, 23, 27, 29, 33, and 21. Plot the points on graph paper (run chart) and determine if the process is stable. Determine the trial central line and control limits. (Hint: count of defects/unit)
