...of relationship and associations on simultaneous activity of partners. On the other hand, it would also be much better if the test of difference was employed in the proportion of time spent in different activities. These are all practical tests in inferential **statistics** that if employed correctly will lead to **statistically** significant results. On the other hand, there was no clear population parameter considering that it was not clear where the couples were coming from. The study would **probably** imply that the selected respondents were representative enough of the entire population of married couples in the world. In this case, it was not clear where these couples were coming from. Since...

...? The type of **statistical** analysis to use in analyzing of data depends on the sample size, the research design used and also the sampling protocol adopted. In analysis of your data from the three researches, both descriptive and inferential **statistics** will be useful. Descriptive **statistics** should be used before inferential **statistics**. The data will be summarized through calculation of measures of central tendency such as mean and median. Range and standard deviation as measures of dispersion/ variation will also be calculated. The data will also be tested for normality and organized into tables or in spreadsheets so as to identify the missing information. Normality...

...in the criminal institutions. Therefore, it is significant to have records of how other similar cases are handled in order to make conclusive claim that other cases of similar classification are given weight than others (Yacouban, 2000). Notably, Yacouban has applied this **statistical** comparison of this **statistical** data to arrive to his conclusion that the international criminal law does not give genocide crimes the weight they deserve. However, other than the use of percentages, Yacouban could have also used **probability** by computing normal curves to the data he obtained (Faherty, 2007). From the normal curve, it will be clear to note which cases are being preferred over which ones....

Therefore, the use of the Bayesian **model** in estimation of this data will combine both the expert-based and data-based approaches into a common stochastic...

so called parabolic antennas;
flashlights and reflectors;
path of a projectile and solar furnace (Jones 2005 n/p).
Some practical applications hyperbolas include:
Optics (lenses for telescopes);
Astronomy (trajectories of comets);
Navigation.
2. **Probability** applications
One area where **probabilities** are widely used nowadays is earthquake predictions (American Geophysical Union 1995 n/p). The **probabilities** of certain geological events that can lead to an earthquake are estimated for a given area and used to formulate important predictions.
Another field where applications of **probabilities** are extremely popular is business. **Probabilities**...

...Topic: **Statistical** Problem A new product has the following profit projections and associated **probabilities**. Profit **probability**
$150,000 0.10
$100,000 0.25
$50,000 0.20
0 0.15
-$50,000 0.20
-$100,000 0.10
a. Use the expected value approach to decide whether to market the new product.
Expected Value = ($150000 * 0.10) + ($100000 * 0.25) + ($50000 * 0.20) + ($0 * 0.15) + (-$50000 * 0.20) + (-$100000 * 0.10) = $30,000.
b. Because of the high dollar values involved, especially the possibility of a $100,000 loss, the marketing vice president has expressed some...

...EBS101: **Statistical** Methods Assignment Sheet 2 For set A, a linear regression line of Y against X2 needs to be plotted. The regression line, alongwith the plotted data-points, is as follows-
The linear regression line passes through all points, and the value of the correlation coefficient is 1 (that is, perfect correlation). Thus, it is concluded that there is a perfect linear association between the given data sets.
For set B, a linear regression line of Y against X needs to be plotted. The regression line, along with the plotted data-points, is as follows-
The linear regression line lies close to most points, and (2.4, 2.6) is an anomaly. The value of the correlation coefficient is 0.96, which represents a fairly strong positive... the...

...**Statistical** Test This section was used to perform preliminary **statistical** test on the data that were collected from who patronize the school cafeteria on their desire to be served with specific soft drinks and how they would be able to determine that the specific drink they demanded was what they were served with. The data were collected based on the hypothesis that the only way to determine the true brand of a product is through taste and not just by looking at the appearance of the product. The assertion was made against the backdrop that there could be imitation of packaging. This section shall therefore deal with the organization, summarization, display, consideration and above all the evaluation of...

...**Statistical** **Models** for Forecasting milk production Introduction Dairy farming is a major economic activity in many countries contributing much to the national gross domestic product (GDP), income, employment and food to many small-scale farmers. The growth of the dairy sub sector has been largely driven by high domestic demand for milk and dairy products due to a growing population (Omondi and Meinderts, 2010). The country’s dairy herd size is the biggest in sub- Saharan Africa (Mugambi et al, 2010).
Although dairy farming sector has a significant contribution to the national economy, household incomes and food security, the industry faces a number of technical, economic and institutional problems in milk production, processing... and...
