From the above summary, the average loss for ten months is $118,358 which is deemed to be the damages for the ten months before Brinks’ contract was terminated.

B. As a Brinks’ Attorney, my objection would be that the damage calculation method considered only a few months; it did not cut across the entire period Brinks had the contract.

Therefore, Ford should recall tires since the total cost for this option is quite lower than that o...

Abstract
In this work, the author explored the role of probability in **inferential** **statistics**. Man has discovered several probability distributions. Some of these probability distributions include the binomial, hypergeometric, normal, chi-square, and several other probability distributions. Populations or **statistics** are assumed to follow one of these several probability distributions and these are used to estimate population parameters as well as test hypotheses on the population. The standard normal distribution, for example, is used to draw inferences on population parameters such as the population mean. The t-**statistics** is used for **inferential** purposes involving small samples or where the population variance is unknown. Finally...

The method is also not sensitive to variation in the value of money over time. However, it is easy to use and can be used to make a quick assessment of investment viability using existing data (Groppelli & Nikbakht, 2006: pp. 157-158).

Net present value (NPV) takes into account the value of money over time and uses the present value of future cash flows (Lasher, 2008: p. 426). This present value is compared with the initial investment and decision taken on whether the investment is viable over the long term or not. NPV is, therefore, a difference between the present value and the initial investment. If NPV is positive, the project is viable, and if it is negative, the project may be rejected. NPV uses the discount r...

A more serious suicide problem in correctional facilities, which has come to the fore in recent times, is the gender disparity in the cases of prisoner self-harm and attempted suicide. It is rather intriguing that while they comprise only about 5% of the prison population, female prisoners are observed to attempt more self-harm and attempt suicide compared to males. Notably, between 20% and 24% of female prisoners self-harm while between 5% and 6% of male inmates self-harm every year. The study also found out that cases of self-harm were 30 times higher in female prisoners compared with the general UK population rates, which were reported to be at 0.6%. Hence, this study seeks to establish whether or not, female prisoners attempt...

It is from this data we get to know more information about the population or universe. The data is obtained from a small portion of a population (sample), carefully selected to represent all population. Analyzing such a small data is easier and cheap as compared to analyzing the whole population. It is worth noting that population is either infinite or finite and sometimes, in the process of analyzing, a sample may be destroyed e.g. testing compression strength in concrete bricks. Therefore, it is advisable that the sample must be representative of the population so that whatever conclusion made based on the sample infer also to the population. This is never absolutely certain hence inductive or statistical inference. The phase of...
