Amazon has recently embarked on a delivery strategy to deliver packages earlier in the day and to a greater number of customers. This strategy involves hiring independent agents to pick up and deliver the packages, allowing for improved performance and on-time Prime delivery fulfillment by both their regular employed delivery fleet and the independent agents.

She monitors her agents for a 10-day period with the following results: Complaints 12 graph goes under this line Day 1 2 11 3 14 4 11 5 12 6 15 7 11 8 14 9 10 5 15 A) Using the Z-Score of 1.96, develop an appropriate Bar Chart by calculating the following: [place a box around each final answer] *Show work. Available points are in (parentheses). Bar Average: (2) Bar Standard Deviation: (2) = UCL: (2) = C-bar + Z(sdC-bar) = LCL: (2) C-bar - Z(sdC-bar) = B) Graph the CLS and identify the data points on the graph.
