(2015). Module 5 – Sampling and Statistical Inference [Critical Thinking file named shoes.xls]. In MTH410 – Quantitative business analysis. Greenwood Village, CO; Author Conclusion The Beltway Shoe Company has taken data points for their western and eastern region for shoe sales. Using statistical data such as mean, median, range, and standard deviation, along with confidence interval estimates for the sale price and days to sell, management is able to understand which region is performing better in profits and days to sell. Further study of the data will allow management to increase profits in both regions by comparing which shoes are selling more quickly and at higher profits. Management is also able to set pricing for shoes based on the data and maintain similar profit results. Understanding and using the data they collected will help to improve profits and reduce inventory, which will increase…

try to estimate and combine the evidence from the data to reach a Bayesian posterior probability distribution. This posterior probability distribution supposedly contains all information about the parameter. Therefore, we could make inferences solely based on this distribution. Lots of literature has addressed the benefits of using this method. In my opinions, Bayesian approach has its advantages in medical research. First, under the situation where researchers cannot recruit enough participants…

Eq.\ref{Bi} is a projection of the attribute vector $I_i$ in the eigenspace spanned by the first $k_c$ eigenbackgrounds, being $\textbf{b}$ the coefficient vector of the combination. In the standard EIG method the number of eigenbackgrounds retained $k_c$ is chosen by fixing a threshold for the last eigenvalue $\lambda_{k_c}$ retained. The background obtained $B_i$ are then subtracted to the original image and a moving object is identified as the regions of the images in which $I_i-B_i$ is…

Condominiums for Sale The cost or real estate can differ from region to region and with size and quality. One factor that greatly effects the sale of a piece of property with a view. Such is the data that will be analyzed herein. Can the data support the fact that there will be buyers willing to pay more for a condominium with a view? Consequently, would a comparable home without a view that is considerably less expensive actually take longer to sell? Overview of the Condominiums for sale The…

the entire word. We will do this exercise with all of the words until she is comfortable doing this without the popsicle stick. This activity should help her to sound out words on her own, when she is reading, which should help her fluency and comprehension. Another factor that Imani seemed to struggle with was inferencing. Inferencing is when you determine a fact or idea based on your life experiences. Imai seemed to struggle with this concept. In order to help her with this concept, I will…

Different types of inferences: What are inferences used for? Whether experimental or review in purpose, most studies have laid out meticulously detailed analyses of the types of inference that exist in their authors’ view of comprehension. The literature has been prolific in distinguishing various types and categories of inference, ranging from thirteen, described in Graesser et al. (1994), nine in Pressley and Afflerbach (1995), to the more usual two, adopted by many more researchers. Even…

time left to write the paragraph, I assessed the table that the students filled out with the evidence, their schema, and the inference, which for the most part covers the information needed in the paragraph. As I looked at the papers, 3 of the students were struggling to put more than the items names, therefore I assume they could not infer or did not understand the question. Other 2 students were not able to finish more than 80% of the table, but they made good inferences. The rest of the…

meets the following two conditions: good inference, and true premises. That is, the conclusion must logically follow from the premises and all the propositions must be true. “The conclusion of a sound argument cannot be false. It has to be true” (Ancell). The indisputable nature of the conclusion is the power of a sound argument. If an argument meets one condition and not the other, it is not considered sound and is therefore flawed. To further understand their faulty nature, one must examine…

Indeed, if it were the case that there was no necessity in nature, “inferencing and reasoning concerning the operations of nature, would, from that moment, be at an end” (Hume 193: 54). However, the idea of necessity arises from the fact that we do find uniformity in nature, which results in the conjunction of similar objects that in turn results in the mind making inferences upon encountering like objects and situations. And it is this uniformity that all people anchor their choices, plans, and…
