Abstract

Regression analysis estimates the value of a random variable (dependent variable) for a given value of an associated independent variable. The regression equation provides the formula for such a calculation. In the present case, which is about the analysis of the dependence of total monthly sales on the monthly customer traffic, the consultant first examines to see if there is a correlation between the two variables. To achieve this, the consultant uses the scatterplot, plotting the points on a graph. After analyzing the scatterplot, the consultant is convinced that there exists a strong positive linear correlation between the two ...

Introduction

The SNAP-25 is the synaptosomal-associated protein 25 which generated different primary and secondary effects on animals and human being including death. The most important symptoms (Huang, 2004) of the SNAP-25 are: ■ Attention deficit hyperactivity disorder: This affects the attention, excessive activity and difficulties in control behavior. Extreme situations may cause death. ■ RS362584 polymorphism in genes causing neuroticism in living beings, including humans. The neuroticism causes anxiety, fear, worry and frustration in individuals. In extreme cases, its causes the death.

The SNAP-25 biologically interrupts and destroys links and the structure of the ribonucleic acid of the cells.

In a laboratory analysis, the degradation of SNAP-25 will cause death if it is degraded to less than 25%. The ...

Analysis

The scatter plot provide a visual representation of the relationship between white pine and the percentage of Penn Sedge. It form the preliminary analysis. The scatter plot shows a negative relationship between the percentage of Penn Sedge and the number of white pine. However, the relationship seems to be weak since the trend line is almost horizontal. Besides, the data points are far away from the trend line.

Further analysis was conducted using regression analysis to test the hypothesis under consideration. The regression results as follows:

The adjusted R square is -0.004. This means that the percentage of Penn Sedge only explains 0.004 percent variation in the number of white pine and approximately 99 percent of the ...

Objectives

The main aims of this experiment are to determine if the oscillation of a mass hung vertically from a spring are an example of simple harmonic motion, to measure the gravitational acceleration of the earth and to determine the accuracy of the experimental results. The value of k (the spring constant) for the spring being used will also be measured and the relationships between the spring constant, mass and period of will also be investigated.

Theory

If a mass is attached to the string, it will stretch and reach equilibrium. The relationship between the spring extension and force applied is ...

INVESTIGATING THE RESISTIVITY OF A WIRE

Electrical resistance is a physical quantity characterizing the properties of the conductor to interfere with the passage of electric current and voltage, which is equal to the ratio of the voltage at the end of the conductor to the current flowing through it (Brown, Forbes T., 2006, p. 43). The electrical resistivity is a physical value that characterizes the ability of a substance to prevent the passage of electric current. The resistance of an electrical circuit can be calculated, with the help of two equations below (Woan, G., 2010). R=VI

R – Resistance (ohms), V – Voltage (volts), I – Current (amps)

R=pLA p – Resistivity (ohm.m) L – Length (meters)

A – Cross-sectional area (meters2)

A physical ...

The cost which the organization incurs the production and acquisition of products and services which it intends to sell is very important. The pricing strategy of the organization is significantly affected by costs. Therefore, costs designed to tackle the challenges of the economic and the noneconomic factors very efficiently. The objective of the costing models is to categorize the factors of the marketing objectives of the company and the mission of the company (Gitman, 2003).

Accurately determination of cost is important in organization to remain profitable. Costing does not only require including direct and indirect cost associated with business ...

2.1. There are two types of risks, known as systematic risk and unsystematic risk. Systematic risk is the one that cannot be mitigated with the help of diversification and strategies; however unsystematic risk is the one that can be mitigated with the help of effective strategies. In terms of quantification, there are three different aspects that are integral known as market risk, credit risk and operational risk. In this particular assignment, all of the analysis will be based on the market risk and its exposure. It has been originated through the Forward and Future Contracts (Christoffersen and Mazzotta, 2004). ...

Question #1

a) Break-even analysis is important to assess the current state of the enterprise and its dynamics, as well as for the development strategy of the company. For the definition of concepts such as break-even point and financial headroom is necessary, first of all, to define the fixed and variable costs. These concepts are used in the solution of almost all kinds of administrative tasks in the system "costs - production volume - profit."

Fixed costs do not depend on the quantity produced.

Example: The company leases land. For this land has to pay a rent of $ 100. This cost is formed regardless of the ...

- A 95% confidence interval for the mean income of shop assistants in a certain city is found to be (£12,000, £15,000). Explain briefly what this means. Would a 99% confidence interval be better than a 95% one? Justify your answer. ANS – It means that there is 95% probability that the value of the parameter i.e. individual incomes of different shop assistants shall lie within the range of £12,000 to £15,000. Yes, 99% confidence level is better than a 95% one as it increases the probability of the incomes of different shop assistants to lie within the defined ...

Question 1

a). Using the ACF graph, a trend is identified, which shows seasonality. The first trough shows the high season whereas the second trough represents the slack. After the ninth period, the graph shifts to the negative side, which may signify a low season. The PACF graph shows that a majority of periods of high are followed by a low period. This, however, is different for some periods where a period of high is followed by two consequent lows. This is a non-linear trend for the Mobile Home Shipment. b). From the autocorrelation analysis, there is an evident time series. A time series is when there is a ...

Summary

It is generally agreed by economists and finance specialists that the 21st century is Africa’s century. Growth in the continent now averages 6% over the last five years. It is believed that for Africa’s development to be sustainable, the largest economies in the four main regional blocs (that is Egypt, Kenya, Nigeria and South Africa) have to be stable economically. The stability of a currency is one attribute of a stable economy. A lot, therefore, can be said about the stability of a country by examining the stability of its currency. Factors contributing to the strength of a country's currency might ...
