Your assignment is as follows:
1. Create a spreadsheet in Excel (or equivalent) that
contains this data and does the following
calculations
automatically:
a. Converts each gas volume measurement to
moles of CO
2
produced
(Use a
PV = nRT to
solve
). Do this twice: one column for 0

a. Expected Return: Discrete Distribution
A stock's return has the following distribution:
| Demand for the Company's Products |
Probability of This Demand Occurring |
Rate of Return if This Demand Occurs (%) |
||
| Weak | 0.1 | -40% | ||
| Below average | 0.2 | -8 | ||
| Average | 0.4 | 13 | ||
| Above average | 0.2 | 40 | ||
| Strong | 0.1 | 65 | ||
| 1.0 | ||||
Calculate the standard deviation. Round your answer to nearest two decimal places.
b. The market and Stock J have the following probability distributions:

The following random numbers have been generated: 44, 30, 26, 09, 49, 13, 33, 89, 13, 37. Simulate 10 hours of arrivals at this station. What is the average number of arrivals during this period?
Part B: The time between arrivals at a drive-through window of a fast-food restaurant follows the distribution given below. The service time distribution is also given in the table in the right column. Use the random numbers provided to simulate the activity of the first five arrivals. Assume that the window opens at 11:00 a.m. and the first arrival is after this, based on the first interarrival time generated.
