...?**Descriptive** Staistics As far as this case study and its level of promise is concerned, it is worthwhile to mention the fact that mean value of 10.75were in this research could be considered as appropriate because it has increased after last entry of 45 weeks. However, if you eliminate this entry the mean of 11 patients in the same study will be 7.64 weeks, which is considerably low from mean of 12 patients. For instance, the standard deviation will also be affected significantly of 11 patients if we eradicate last entry. In simple words, the results are not accurate because the last patient’s survival of 45 weeks is an exceptional entry that has alone a considerable impact on measures of central tendency in this study.

Do not reject Ho, because the calculated value is not fall in the critical region.
Conclusion:
Do not reject null hypothesis so we conclude that there is no significant linear association/relationship between level of popularity and math test score.

Whether legal or not, every year millions of individual women around the world— of all cultural, religious, and economic backgrounds— seek out abortion when they cannot carry a pregnancy to term.

At present almost two-thirds of the world’s women live in countries where abortion may be legally obtained for a broad range of social, economic or personal reasons. When abortion is made legal, available and safe, women’s reproductive health improves. When women can avoid births that are unwanted, mistimed, or too numerous, their children are more likely to survive and be healthy.

It has long been recognized that the number of abortions can be effectively reduced by educating people on...

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...
