Th Does the data contain any outliers? If yes, should those outliers be left in the data set for analysis or removed? Explain. Using Excel, create and insert a frequency distribution and histogram of the box weights. Use 10 classes to build the frequency distribution. Based on (a.) the descriptive statistics, (b.) the histogram, and (c.) the empirical rule, does it appear that the box weights follow a normal distribution with a symmetric bell-shaped curve? Justify your response with your data analysis. Assuming the package weights are normally distributed, convert the MAV value to a z-score using the formula z = (LMAV – mean)/standard deviation. What is the probability that any individual package weight will fall below the LMAV of 599.5 grams? Does this pose a risk to the company? Based on your analysis, should management have any concerns about the packaging process being out of compliance with the government standards? Explain Based on your analysis, should management have any…
