Quantitative Techniques in Statistics

Due to financial hardship, the Nyke shoe company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes – regardless of height or gender of the wearer. In no more 5-10 pages (including figures), explain your recommendations, using statistical evidence to support your findings. The data found are below:

a. For each year, create tables of counts of gender and of nationality. Then create column charts of

In order to succeed, it is fundamental that businesses satisfy consumers’ needs (and desires) for goods and services. Appropriate market research provides the data necessary to understand those needs and respond to them effectively and profitably. Kudler Fine Foods (KFF) has performed market research in the past. Some of that research has been helpful; some has not. Additional market research is needed for KFF to reach a larger share of the market and increase profitability.

Correlation of these to an accurate GIS database with up to date information on chimney access and sleigh parking. Previous quality and quantity of carrots and mince pies put in notes.

To view the research on a nominal scale, the research data can be drawn from the type of class. The word nominal is derived from the root word in Latin for name (Usable Stats, 2013). The name of the class, Psychological Statistics, is the nominal measurement for this research. When conducting this study, the study will only be measured during the course of this specific class. The results could drastically change when considering another type of class such as Quantitative Literacy as the cognitive understanding of such a collegic math class may be more optimal through a different course-delivery format.

Compare and contrast quantitative and qualitative methods on each of the elements listed. Please use scholarly, academic literature to support your response.

The information in the table below refers to the 2008 model year product line of BMW automobiles. Identify the Individuals, variables, and data corresponding to the variables in the table below. Determine whether each variable is qualitative, continuous, or, discrete. Please refer to problems #51 and #53 on page 13 for examples.

Assuming unequal variances, the two sampled t-Test was applied on the data sets of female and male shoe sizes with the alpha value of 0.05. The null hypothesis was that the female and male shoe sizes have an equal mean while the alternative hypothesis was that female and male shoe sizes do not have an equal mean. With the degrees of freedom being 27, the t-statistic is -8.16. The probability that -8.16 is ≤ -1.70 is 4.5×10-9 for the one-tailed test. Also, the probability that -8.16 is ≤ ±2.05. is 9.1×10-9 for the two-tailed test. Given that both probabilities are under the alpha value of 0.05, the null hypothesis is therefore rejected, and the alternative hypothesis is accepted at the 95% confidence level.

A company with factories located in New York and Michigan produce yarn, using two different types of machines; JC980 and VH80. Each factory uses only one machine type. The sample size is at 1 391 factories.

To perform a certain type of blood analysis, lab technicians must perform two procedures. The first procedure requires either one or two separate steps, and the second procedure requires either one, two, or three steps.

Well I am in the Army, and I am the Administrative supervisor for the dining facility, and we use statistics to help us track several things. The dining facility I work in feeds Soldiers and civilians, contractors and Department of Defense employees. The groups of personnel listed above must be tracked and managed separately so we can determine how often each group dine in and how frequently. Statistics gives us the tools to create charts and graphs that enable my Soldiers to track and monitor how often each group eats in our facility and how frequently (Mirabella, 2011). Statistics allows us to keep a realistic track record of diners in our facility. By having accurate information on the number of patrons dining at our establishment on

c. Note the ways in which the means and standard deviations differ, and speculate on the possible meaning of these differences, presuming that they are representative of U.S. governors and large corporations’ CEOs in general.
