The expansion of the Istanbul International Airport has drawn media attention for its revolutionised baggage service which shortened the time a passenger needed to collect his or her baggage. To gauge the performance of its newly-installed baggage carousel, the department of aviation services has collected a random dataset on the number of bags per minute handled by Baggage Carousel A and Baggage Carousel B. These are two different carousels. You would like to summarise the dataset, compare the two carousels and reportto the department of aviation services. Your answers should address the following:

1. Choose appropriate graphs to visualise the dataset and provide relevant descriptive statistics and a brief commentary.

2. Compute the average time a passenger needs to wait to see the next piece of baggage. State the assumption you need to make this computation. Hint: what is the assumption behind modelling inter-arrival waiting time as an exponentially distributed variable?

3. Based on your assumptions for both carousels, compute (a) the probability that in one minute there are less than 7 bags and (b) the probability that in one minute there are less than 10 bags. Compare your computed results to what you observe from the data.

4. Explain why you do or do not think your assumption is valid for this dataset.

John Decides to make 10 end-of year deposits of $10,000 into a fund starting one year from now. He is planning to withdraw $20,000 each year for 5 years, starting one year after the last deposit. The fund pays 8% per year compounded annually. Determine the balance in the fund immediately after the last withdrawal.

A railroad car of mass 35000 kg moving at 4.00 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 2.00 m/s.

b) How much kinetic energy is lost in the collision?

8. (Put-Call Parity) XYZ stock is trading at $40. The effective annual interest rate is 5%, so that 100 dollars lent for 1 year will return 105 dollars. One year call premiums are 9, 4, and 2 for strike prices of 35, 40, and 45, respectively. Draw a profit graph (or make a table) for the following strategy: buy one 45 strike call, sell one 40 strike put.

Chapter 8. Flexible Budgets, Standard Costs, and Variance Analysis...answer them all.

8–7 What does a flexible budget enable that a simple comparison of the planning budget to actual results does not do?

8–9 What is a quantity standard? What is a price standard?

8–10 Why are separate price and quantity variances computed?

8–11 Who is generally responsible for the materials price variance? The materials quantity variance? The labor efficiency variance?

8–12 The materials price variance can be computed at what two different points in time? Which point is better? Why?

Suppose that ZX Inc. is currently selling at $50 per share. You buy 200 shares, using $5,000 of your own money and borrowing the remainder of the purchase price from your broker. The rate on the margin loan is 5%.

1. What is the profit or loss $ in the net worth of your brokerage account if the price of ZX Inc. changes to $46?

2. What is the profit or loss $ in the net worth of your brokerage account if the price of ZX Inc. changes to $50?

3. What is the profit or loss $ in the net worth of your brokerage account if the price of ZX Inc. changes to $54?

4. What is the rate of return on your margined position (assuming again that you invest $5,000 of your own money) if ZX Inc. is selling after one year at $46 (use whole number percentage with two decimals rounded up/down - i.e. 0.3245 input 32.45)?

5. What is the rate of return on your margined position (assuming again that you invest $5,000 of your own money) if ZX Inc. is selling after one year at $50 (use whole number percentage with two decimals rounded up/down - i.e. 0.3245 input 32.45)?

6. What is the rate of return on your margined position (assuming again that you invest $5,000 of your own money) if ZX Inc. is selling after one year at $54 (use whole number percentage with two decimals rounded up/down - i.e. 0.3245 input 32.45)?

(a) complete the table to show the cumulative frequency

(b) using the scale of 1 cm to represent $5 on the horizontal axis and 1cm to represent 5 students on the vertical axis, draw the cumulative frequency graph for the data.

(marks will be awarded for axis appropriately labelled, points correctly plotted and a smooth curve carefully drawn)

(c) use your graph to estimate (i) the median amount of money spent (ii)the probability that a student chosen at random spent less than $23 during the week.

show on your graph, using broken lines, how these estimates were determined.
