Please share any formulas (including on Excel) and how you got your work. I genuinely do not understand any of this.

A quality consultant was asked to analyze the data from order errors at the Audubon Books, Inc., distribution center as shown in the table below. The data represent a typical order processed in each month and show the errors found in those orders. Any order can have errors from a number of causes, e.g., wrong item and incorrect customer information. Develop a run chart, a frequency histogram, and a u-chart for these data. What insights do you get from each chart? What would you advise the distribution center manager to do about the errors?
