The historical roots on Return on Investments (ROI) have an extensive historical background which involves the Du Pont system. It is significant to illustrate the major history behind the Return on Investments (ROI) and how the Du Pont system started.

In addition to (ROI) share the common class of profitability ratios. Several examples will show how Return on Investments (ROI) and the Du Pont

The historical roots on Return on Investments (ROI) have an extensive historical background which involves the Du Pont system. It is significant to illustrate the major history behind the Return on Investments (ROI) and how the Du Pont system started. The purpose of the Return on Investment (ROI) is to evaluate the efficiency of an investment or compare the efficiency of various investments. In addition to (ROI) share the common class of profitability ratios. Several examples will show how Return on Investments (ROI) and the Du Pont system has established life-long formulas to help indicate growth or decline on financial investments.

Investment performance can be measured in many different ways. Tracking the investment’s return is a simple way of measuring investment

Projected Rate of Investment is a metric used to evaluate the efficiency of an investment. It is also used to compare the efficiency of a number of different investments. It measures the amount of return on an investment relative to the investment’s cost. It is important because it is the most common profitability ratio. Because ROI is measured as a percentage, it can be easily compared with returns from other investments, allowing one to measure a variety of types of investments against one another.

§  Investment Performance is a complicated subject §  Theoretically correct measures are difficult to construct §  Different statistics or measures are appropriate for different types of investment decisions or portfolios §  Many industry and academic measures are different §  The nature of active management leads to measurement problems

A) $1B) $2C) $0.50D) $0.25Answer: AUse the following to answer 24-27The discrete random variable X is the number of students that show up for Professor Smith's office hours on Monday afternoons. The table below shows the probability distribution for X24. What is the E(X) for this distribution?A) 0B) 1C) 1.5D) 2Answer: BE ( X ) = 0 * .40 + 1 *.30 + 2 *.20 + 3*.10= .30 +.40 +.30= 125. What is the probability that at least 1 student comes to office hours on any given Monday?A) .30B) .40C) .50D) .60Answer: DP ( X ≥ 1 ) = P ( X = 1) + P ( X = 2 ) + P ( X = 3)= .30 +.20 +.10= 0.6026. What is the probability that fewer than 2 students come to office hours on any given

Please complete the following problems in a Word document. Each problem is worth 3 points.

b) quartiles suggest the 25% of samples are less than Q1, 25% between Q1 and Q2, 25% between Q2 and Q3, and 25% greater than Q3

In order to undergo the procedure of calculating the performance of the clients chosen assets, historical financial performance will be needed to assist to calculate how these organisations have delivered, and will deliver returns to their shareholders. Below will be the use of several financial ratios to analyse the figures of specific investment options selected by the client. These financial ratios include the rate of return, average return, risk rate and the Sharpe ratio.

The standard deviation of the checking account balances 596905 and the range is 2525. The first quartile shows that 25 percent of the data are lower 1122.50 and the third quartile shows that 75 percent of the data are

1. When testing for independence in a contingency table with 3 rows and 4 columns, there are ________ degrees of freedom.

In the business world investments are made, taking into account the discounted cash flow (DCF) analysis, net present value (NPV) and basically the thumb rule being of return on investment (ROI) is not too low and internal rate of return (IRR) is not too close to the discounted rate. These factors are the frame work where in companies/business depend on making an investment.

Now each of these try to demand and command attention in furtherance of their own cause. All these also can work towards reducing the gap between the capital investment and returns (profit/loss). It is prudent to manage these denominators in a way that reverses the trend and makes returns, a healthy multiple of capital investment.

b) Suppose you perform a similar survey at IIMA with 24 randomly selected students; the sample mean and the sample standard deviation were 4.5 and 2.8 respectively. What will be a 99% confidence interval of the population mean

3. The data to be collected will be compared for the purpose of giving remedial measures.
