The assignment will be marked out of 50. Marks for each question are shown.

Data for analysis:
Suppose that you are working for an environmental group on household electricity consumption. You are primarily interested in quantifying what factors could affect the household electricity consumption. The environmental group provided a data set that contained the information of 50 randomly selected households in Western Sydney. The data are recorded in an EXCEL file that you can download from the course web site.

Q1a (8 marks)

The leader of the environmental group suspects that homes (referred to as population 1) consume more electricity than units (referred to as population 2). Perform a hypothesis test to validate such suspicion. You must clearly state your null and alternative hypothesis, your conclusions, and the related output that lead to your conclusions. Use α=0.05 and assume unequal variances.

Q1b (8 marks)

However, the test in Q1 does not take the size of the building into considerations. So you compute the electricity consumption per week per square meter. We call this the electricity consumption rate. Perform a hypothesis to verify if the electricity consumption rate of homes is higher than that of units. You must clearly state your null and alternative hypothesis, your conclusions, and the related output that lead to your conclusions. Use α=0.05 and assume unequal variances. Q1c (4 marks)

Based on your analysis in Q1a and Q1b, is it true that homes consume more electricity...

...THE NATURE OF RESOURCE COST STRUCTURE AND THE PRACTICAL SIGNIFICANCE OF DIFFERENT COSTS
2.2 THE FACTORS INFLUENCING OPTIMUM SIZE AND THE SIGNIFICANCE OF DEMAND AND SUPPLY RELATIONSHIPS
2.3 UNDERSTANDING OF THE RELEVANCE AND LIMITATIONS OF ECONOMIC THEORY TO MANAGE DECISIONS
3. CONCLUSION
1. INTRODUCTION:
From the economic perspective, there are a full range of wants from individuals, firms and government but there is only a few number of resources or factors of production such as land, labour, capital and enterprise. The raw material will come from land, taking the example of oil, gas. The labour relates to the individuals able to work. The capital covers machinery, computers, offices or shops for retail people. Enterprise will bring all of these factors together and allow them to produce goods and services in order to make a profit. This individual report will be identifying the nature of resource cost structure and the practical significance of different cost. It will also explain the factors influencing optimum size and the significance of demand and supply relationships. It will finally demonstrate an understanding of the relevance and limitations of economic theory to management decisions.

...of 1000 flights and proportions of three routes in the sample. He divides them into different sub-groups such as satisfaction, refreshments and departure time and then selects proportionally to highlight specific subgroup within the population. The reasons why Mr Kwok used this sampling method are that the cost per observation in the survey may be reduced and it also enables to increase the accuracy at a given cost.

BusinessStatistics II: Research Paper
Robert Franjieh
April 19, 2015
Introduction
This research paper will be designed to answer a couple questions regarding statistics about the Buena School District school bus data. The questions I will be discussing and answering will be based on maintenance of the school busses. The question prepared is; is it cheaper or more expensive to run Thompson, Bluebird, or Keiser busses? I will also be addressing another question based on other variables by removing the gas types and making it just one gas type instead of two; does gas type have anything to do with the maintenance of the Thompson, Bluebird and Keiser busses when removed from the regression? In order to answer these questions, both regressions and data sets do not contain the 6 passenger busses, being there are only very few and that they might skew the regression.
To explain a little about maintenance on busses, a routine oil change can run anywhere between $150-$250. Diesel engines can go 6,000 to 10,000 miles between oil changes depending on idling time and driving time. If you buy a used bus, one of the first major components that may fail you is the turbocharger. Expect to pay $1,700-$2,000 for a replacement. A tire for a bus can easily cost anywhere between $400-$600. This does not include the price of installation. If your bus should break down, you will need a heavy-duty...

...Null Hypothesis:Ho: p = 50.%
Alternative Hypothesis:H1: p > 50.%
Level of significance=alpha (a) = 0.10 or 10.0%
This is a one tailed test because we are testing the area in the right tail
Since the sample size is large we will use z distribution
z critical= 1.2816
Decision rule
If the sample z value > z critical, 1.2816 reject Null Hypothesis
If the sample z value < z critical , 1.2816 accept Null Hypothesis
Alternatively:
If p value < significance level , 0.1 reject Null Hypothesis
If p value > significance level , 0.1 Accept Null Hypothesis
Decision rule: If the area in the right tails is less than the level of significance (0.10 0r 10%) reject the Null Hypothesis
Or alternatively z statistic computed for the sample should be lesser than z corresponding to 10% significance level
p= 50.00%
q= 50.00%
n= 60
sp=standard error of proportion=square root of (pq/n)= 6.4550% =square root of ( 50.% * 50.% / 60)
sample proportion= 63.33% =38/60
z=(sample proportion-population proportion)/ standard error= 2.0651 =(63.33%-50.%)/6.455%
P-value:
This is a one tailed test therefore area in one of the tails is checked
Cumulative probability corresponding to the obtained z value of 2.0651 is 98.05%
Thus the area in the right tail= 1.95% =100% -98.05%
P-value= 1.95%
For the null hypothesis to hold the area in the right tail should at least be greater than 10.00%
Since this condition is not...

Total Marks: 40
Worth: 20% of final assessment
This assignment requires a considerable amount of computer work and written comment. You may need to seek guidance from your tutor along the way. Do not leave things until too late. Each question carefully describes what you are required to do, so please follow these carefully.
In this assignment, you will again examine data from a fruit and vegetable market that supplies fresh produce to supermarket outlets in NSW and Victoria. The market is conducting an evaluation of customers in Sydney and Melbourne. The fruit and vegetable market wants to examine the % of produce damage at each of the outlets and is particularly interested in the relationship between % produce damage with: the type of produce; the customer; and, quantity (sold per day).
The data collected is contained in a file called ‘Fruit and Veggie Market.xls’ and the columns of the file contain the following information:
Column | Name | Description |
A | ID Number | Customer Number |
B | Customer | 1= Coles2= Private3= Safeway |
C | City | 1= Sydney2= Melbourne |
D | Produce | 1= Apple2= Orange3= Potato4= Tomato |
E | Quantity (sold/day) | Total quantity of produce sold per day |
F | Price$/kg | Price in dollars per kilogram |
G | % of produce damage | Percentage of produce damaged |
