Answer In order to obtain a sample size for a proportional, formula is used in like with well-known population size, clearly stipulated sample proportion and the margin of error. Therefore, to find …………….

Solution Answer Statistically, a sample is that percentage of the entire population. Deciding on a given sample size depends on factors such as the original population size. In order to obtain…………………………………………………….

Answer In order to obtain the confidence intervals for a ratio, we calculate group sample sizes that are necessary in achieving specific interval width of the ratio of distinct and two independent data proportions. Here, an assumption is ………………………………………

Answer The t-distribution is most useful for sample sizes which are small, or when the deviation of the population standard is not known, or both. Therefore, one must use ……………………………..

Answers The confidence level in statistics is defined as that probability level in which the value of a given parameter falls within a given range of values. It indicates the probability at which the estimate of a statistical parameter such as the mean in a sample survey is similarly true […]

Answers In statistics, a sampling distribution is that probability distribution mostly of a statistical data that is obtained from a very large number of samples drawn from a given population. It is the distribution of frequencies of a range of district outcomes ……

In the similar way as weather forecast is used to predict future atmosphere behaviors, there exist numerous real examples of the use of probability. One of the real-life examples of the use of probability in predicting future events is the sports statistics. Notably, in the world of sports, football or […]

Bayes’ theorem is a probability theory that provides a way for figuring out conditional probability (Puga, Krzywinski, & Altman, 2015). For a conditional probability, the probability of an event happening is based on it having same relationship to one or more other event. For instance, the probability of having a […]

In mathematical predictions, a graphic organizer is a learning and teaching tool used to organize ideas and information in such a way that they are made easy to internalize and comprehend. According to Colliot,  & Jamet,  (2018), graphic organizer normally integrates text and visuals, thus, showing the relationships and connections […]
