Assignment Brief:
Do people park centrally
in parking bays??In this assignment you are to: a) test a statistical
hypothesis thatâcars are parked centrally in parking baysâ
using the data
supplied to you, and b) report your findings.
In this assignment,
two variables are used to determine whether or not a car is centrally parked.
These are a) D1, the distance between the left tyre and the left boundary
line of the parking bay, and b) D2, the distance between the right tyre and
the right boundary line of the parking bay. A car is judged to be centrally
parked if |D1 â D2| < P. The parameter P is set to 150mm, i.e. an allowable parking tolerance. To obtain the data for the statistical test, you need to run a computer program (car-park-data) installed on PC in the Operations Management (OM) lab. The software would allow you to randomly generate a set of fifty (50) samples of cars parked in parking bays. The sampled dataset containing computer estimated values of D1 and D2 of each car in the sample would be emailed to you. You are required to: 1.Log on to the PC and run the car-park-data computer program to obtain the sample data. The data set will be sent to you via email. ? 2.Conduct a statistical analysis and reporting of the sample data you received, covering the following tasks: . a) Effective presentation of the data. ? . b) Summarising the data using appropriate numerical descriptive measures. ? . c) Test of hypothesis thatâcars are parked centrally in parking baysâbased on the dataset. ? . d) Discussion of results and conclusions. ? Cite relevant literature to support your work. The report must not exceed 2000 words. Please state the word count of your report on cover page. The assignment should be done individually. .jpg">
