The author explores how statistics, especially probability knowledge can be used in various forms of gambling to gain an advantage over other players so as to win big (Thomson, 2009). The author talks about three strategies that can be used in gambling. First, the article talks about exploiting randomness in casino games.

The author states that statistics is a wide field of study, probably one of the broadest disciplines available, with a plethora of applications too. The topic of ‘Fields of Application of Statistics’ is a rich topic in itself and one that sparks a lot of interest both to scholars and professions globally.
Of the 44 depressed subjects, 13 were treated with antidepressants. This was 29% of the subjects. However, I think that the number of people who received the antidepressants was not enough. 29% was a small proportion to use for an experiment. However, the number used produced sufficient results and this was a result of the scarcity of mental health care in the rural areas.
It is a score arrived at after taking a set of standardized tests, and it acts as an indicator of academic prowess. People with scores under 70 are said to be mentally retarded while those with scores over 130 regarded as having a superior IQ (Boeree, 2003). The
This establishes significance of factors that employers consider in determining wage rates to employees, for possible variation of the factors towards increased pay. Employers, however, seek to minimize their costs and this establishes a limit to maximum wage rates that

The purpose of the study conducted by Pettifor et al. (2009) was to estimate the effect of the distribution of LLINs free of charge to pregnant women at their first antenatal clinic visit in the Democratic Republic of the Congo (DRC). Previous studies showed that the distribution of LLINs free of charge in other African countries resulted in a significant increase in their use.

Statistics involves collecting data, organizing the data and analysing it to aid its presentation in a meaningful way to provide information about a given phenomenon. Statistics may fall under two main categories namely descriptive or inferential.

The factors are used to assert the viability of the hypothesis statement. Random sampling does not portray bias to any part of the population (Duttalo, 89). Convenience sample does not give a true analysis of the population because researchers take what is convenient for them.
For instance, the author notes that young people in their adolescence (presumably represented by the group aged 18 – 20 in this study) are more likely to have a lower education compared to the older individuals in their late twenties and
The author refers to the Seasonal Decomposition output in the BUS 305 Midterm Exhibits file. This output was created for a quarterly time series of production values. The actual value for observation 6 was 254.7. Calculate the deseasonalized value for observation 6 (round the final answer to two decimal places).
The author states that the evidence-based process is based on medical-related reference resources. There are some differences between program evaluation and evidence-based processes as analyzed in this paper. Designing a program evaluation involves asking some questions considering the purposes of conducting the evaluation.

The first null hypothesis is rejected at 0.05 significance level as the associated P-value is found to be less than 0.05. It shows that there is a significant difference amongst mean ages of male and female employees. The second null hypothesis is also rejected at 0.05 significance level as the associated P-value is found to be less than 0.05.

The assignment model facilitates solving transportation problems through the explicit identification of the objective function, the decision variables and the constraints.
From the viewpoint of demand and supply, the six plants are considered as supply sources and three waste sites are demands sites; both of them have limitation, which is expressed as a quantity that can be supplied and stored. The
After the collection of data and information, multi-linear regression is carried out, in analyzing and interpreting the information. The research question focuses on whether movies break even at the initial release in the box office.
The study is grounded in the supposed suppression of lung cancer by apoptosis that is activated through the intrinsic Bcl-2 pathway, as well as the extrinsic death receptor pathway. The objective of this study was to find out whether there are genetic variants of Bcl-2 that are associated with susceptibility to lung cancer and its prognosis in Chinese men.

Statistics plays a big role in informing the audience, changing their opinions as well as creating curiosity. It will look at how analysis of variance can be used in enhancing understanding of a given issue. Ideally, ANOVA is best suited when an analyst wishes to compare the means of at least two groups or levels of independent variables.

The odd’s ratio for the relationship between the risk of heart disease and smoking is 1.55 which is slightly over the 1.0 value. Since the odd ratio measures the relationship between the risk of heart disease and exposure to smoking, we can assume that the study generating these results is not biased and hence infer that the risk of heart disease is 1.55 times for cigarette smokers than for non-smokers.
