. Root depth for grasses and shrubs in a type of soil known as glacial outwash was studied in Yellowstone National Park. It was found that the root depth in this type of soil is a normally distributed random variable with standard deviation 8.94 inches. (a) In a proposed study region of glacial outwash, how many plants should be carefully dug up and studied to be 90% sure that the sample mean root depth is within 0.5 inches of the population root depth? (b) How many to be 90% sure that it is within 0.25 inches? (Is there any obvious relationship to the answer of part (a)?

Dizzy Inc. is the only operator of themed amusement parks (DizzyWorld). Dizzy’s production function (which, oddly, relies only on labor) is given by:

Eminent domain is the constitutional principle that the government can take private property from an owner for a public purpose with fair compensation. Examples would be to build an airport, a park, or a highway.

Develop a simple MIS (Management Information System) that consists of a simple database (a text file). The system manages to dynamically input record/data into the database. The data from the database can be sorted, searched and updated. User also should be able to add new records/data, remove any data and etc.
Here are some ideas of MIS that can be developed:
1. Hotel reservation system.
2. Students management system.
3. Payroll management system.
4. Bus/Railway/Plane ticketing system.
5. Clinic record management system.
