Please show all work! Thank you! :)

Solve these problems and upload your solution to Canvas. You can solve them "by hand" b. Based on your calculations, conclude whether the test is random or non-random. or using Excel. Show all your work (typed in the document or pasting a scanned image of your handwritten solution). Save your solution document in a .pdf file and upload it to Canvas along with an Excel file for calculations performed in Excel. Problem 1 (18 points) c. Should the process be investigated due to nonrandom variation? (Yes or No) The following is a control chart for the average number of minor errors in 22 service reports. a. Determine the observed number of runs (median, and up/down), expected number of runs, standard deviation, and the ztest value for the median and up/down test. Use z=+/2 to compare your z test scores. (Negative amounts, if any, should be indicated by a minus sign. Round your answers to 2 decimal places.) Please use the table below to summarize your answer.
