Statcalc Case Study

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:

Statistics provides us with very useful tools and techniques that aide us in dealing with real world scenarios. I have been able to learn several useful concepts by studying statistics that can aide me in making rational and informed decisions that are supported by the analysis results. Statistics as a discipline is the application and development of various processes put in place to gather, interpret, and analyse the information. The quantification of biological, social, and scientific phenomenons, design and analysis of experiments and surveys, and application of

Joel has done excellent work with all of the topics we’ve studied. He missed quite a few days of school this semester, but managed to keep up with the material very well. Joel has a very organized and methodical approach to his work. His serious attitude makes him a good candidate for taking on the challenge of AP Statistics next year. I look forward to working with Joel the rest of the semester.

In this activity you will collect data and then perform statistical analyses to determine measures of central tendency and variation of the data. You will also represent

• Provide at least two examples or problem situations in which statistics was used or could be used.

Descriptive statistics are digits that are used to summarize and describe a given range of data (Klenke, 2008). Basic descriptive data includes, mean, median, mode, variance and standard deviation. The data can be rearranged in an ascending order as follows:

The Changing the Stats Center is a newly found program in North Baton Rouge, Louisiana. Changing the Stats Center will not only work with North Baton Rouge but will work with all of East Baton Rouge Parish juveniles and their families. The purpose of the center is to work with African American juvenile delinquents and their families and give them the support they need to carry functions of being a productive citizen. Juvenile delinquents are usually between the age 10 and 17 and have committed a crime. Crimes are illegal activities.

The goal of our agency is to have East Baton Rouge Parish report a decrease in juvenile crimes and juvenile arrest. We will offer two types of therapy treatments, Functional Family Therapy, and Multisystemic Therapy. We will also work alongside with East Baton Rouge Parish to provide Intensive Protective Supervision.

9. Using the range rule of thumb estimate the standard deviation for the number of credit hours students in this sample are taking and the shoe sizes of the females in the class. Then using StatCrunch compute the actual standard deviation. Compare the results.

A statistic is a numerical summary of a sample and a parameter is a numerical summary of a population.

Statistics uses math to determine whether or not an experiment happened by chance. In other words, it determines the probability of your results being by chance or if it is factual data. The mathematical ways of determining probably include looking at mean, standard deviation, mode, and median. This experiment will use statistics to test the probability.

I believe that in the verge of realization, in everyday life’s undertaking we are facing and practicing statistics. I was being into a serious dedication of understanding the underlined concepts of statistics and the necessary usefulness in conducting a survey. In fact, throughout the course, I did learn many factors that became useful in contacting a survey research. according to Walker et al. (2011). However, my success could not be possible without the appreciation and support of my teachers, discussion groups, and class presentations.in addition, the misguided notion of statistics being a tough course was proven otherwise since I realized that statistics make a lot of sense not only in survey research in personal life, especially in budgeting and planning for individual routines. Furthermore, the following paper provides a vivid explanation of my reflection of the survey class, with more attention paid to the concepts of statistics.

A pharmaceutical company is testing the effectiveness of a new drug for lowering cholesterol. As part of this trial, they wish to determine whether there is a difference between the effectiveness for women and for men. Using   = .05, what is the value the test statistic?

This case problem is related to a property purchase strategy. The president of Oceanview is deciding whether to bid for a property to build and sell condominiums. However, this depends on whether the state can change the zoning of the property to permit construction of condominiums. Here, the decision is whether to bid for the property, and chance events are firstly, whether the bid can be successful, and secondly, whether the state will approve the zoning change. To assess the likelihood that the state will approve the zoning change, the president can hire a market research service. Hence, the president is facing another decision as

The business model of SAS is such that it in general it offers services coupled with software. Unlike typical firms in the industry it follows an annual software subscription model. Rather than sell its software, SAS leases to its customers - a strategy of immense importance in understanding the company’s relationship to its users. The fact that leases must be renewable annually creates a tremendous emphasis on customer satisfaction and quality in addition to stabilising its revenue. Furthermore, its products are made based on what customers require and its developmental process is almost wholly customer driven. There is also a strong focus on employee satisfaction leading to customer retention and loyalty which SAS
