Valtec Electronics fills orders for its electronic components and parts by truck to customers through several distribution centers. A measure of its supply chain responsiveness is order fulfillment lead time, which is the number of days from when a company receives an order to when it is delivered to the customer. A distribution center manager has taken 20 samples of 5 orders each during the month and recorded the lead time for each as follows: Sample 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1.3 2.1 4.2 1.6 2.6 0.8 2.6 3.4 3.1 2.4 1.9 6.1 1.2 2.4 3.7 3.6 0.4 17 18 19 2.4 1.2 3.3 2.1 3 2.7 3.5 6.1 1.8 3.6 3 1.5 1.4 1.9 5.8 4.5 3.1 1.4 1.5 2.8 2.5 2.2 1.8 4.8 5.9 4.4 2.7 3.4 0.4 4.9 2.1 5.2 3.4 2.8 4.5 2.9 3.4 2.5 7 1.4 3.3 2.7 4.8 1.7 1.8 6.5 4.8 2.9 3.4 4.4 3.6 2.9 5.2 20 4.7 2 2 1.8 a.
