The Yum and Yee food truck near the business school serves customers during lunch hour by taking orders and making fresh batches of stir-fry. Customers have only one choice during the lunch hour so that Y&Y can maximize the number of customers served. Assume that each customer places just one lunch order, and all lunch orders are the same size: one unit of stir-fry. The stir-fry cooking works in this manner. First, one person cooks a batch of orders in a wok. The cooking depends upon the number of orders in the batch. The time to cook just one order is 3 minutes. For each additional order in the batch, it takes 0.5 minute more to cook. Thus, cooking two orders in a batch takes 3.5 minutes, cooking three orders takes 4 minutes, and so on. The other process is bagging and accepting payments (done by a separate person), which takes 0.80 minute per order.

a. What is the setup time of this process?

b. If Y&Y operates with batch sizes of 6 units, what is their process capacity (in orders per minute)?

c. If Yum and Yee operates with sizes of 10 units, what is the utilization of the work (assume there is sample demand)?

d. Calculate the batch size (in orders) that maximizes the overall flow rate (assume these is sample demand)?

Question 1: In order to get a better understanding of which types of people buy their product, a large company wanted to estimate the proportion of customers who are considered low income. They took a random sample (a very small subset) of 500 customers and found that 210 were low income.

a) Check to see if conditions (there are 4) are met to have a valid confidence interval.

b) What would happen to the distribution of sample proportions if one the first three conditions are not met (sample size conditions)?

c) Construct an approximate 95% confidence interval for the proportion of low-income customers.

d) Interpret the interval found in “c”.
e) Calculate the confidence interval width of the interval created in “c”
f) If were to calculate an 85% confidence interval what z* values would you use? g) What do the values in “f” represent conceptually?
h) Which confidence interval would be more precise (smaller width); 95% or 85%?

i) Before the company took its initial sample (They did not take the 500 observation sample yet), they ideally wanted to have a confidence interval width of 0.048 when creating an approximate 95% confidence interval. What is the least amount of people they needed to sample in order to guarantee there confidence interval width would not be larger than 0.048.

Bad debts are provided for as a percentage of credit sates. The accountant calculates the percentage annually
by using the experience of the three years prior to the current year. The formula is bad debts written off less
recoveries expressed as a percentage of the credit sales for the same period. Total collections from customers
amounted to P2,760,40. This amount included P50,000 for which the goods are to be delivered next year. During
the year. The company recorded the bad debts written off as bad debts expense
