Deviation

– 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…

This assignment will address a one way ANOVA between the variables of section and guiz 3 from the grades.sav data sample Data File Description 1. The context of the data set is based on a sample size of 105 students that states their first and last names and are assigned separate id numbers. The sample contains variables that include the variables to be addressed in this assignment. 2. The variables used in this are section and quiz 3. The section variable, or the predictor variable has a…

motion. The velocity is used in the equation to determine acceleration, therefore, the graphs end up looking similar to each other (both trend lines tend to increase when moving rightward). The standard deviation for velocity is calculated to be 2.26 ± 0.8023 m/s. On the other hand, the standard deviation for acceleration is 5.566 ± 0.4453 m/s2. In addition to that, the accelerations from each testing height are also compared to the theoretical acceleration (9.8 m/s2). The lowest percent error…

how far apart the data points are in relation to the mean. It is helpful when calculating the probability of future events. Standard deviation is a measure of how spread out numbers are and we use the variance of data to calculate it. In order to calculate the standard deviation you take the square root of the sample variance. The combination of standard deviation and mean will allow you to know the majority of data sample. It’s important to understand there is a hierarchy in the level of…

Cellular respiration is “The series of metabolic processes by which living cells produce energy through the oxidation of organic substances” (dictionary.com). These metabolic processes are fueled through O2 consumption. The equation of cellular respiration is as follows: C6H12O6 + O2 ---> CO2 + H2O + ATP (Pidwirny). The actual pathways of cellular respiration are glycolysis, pyruvate oxidation, and oxidative-phosphorylation (Campbell pg. 166). The big picture problem is the rate at which this…

It is well known that the temperature that a plant is grown in greatly affects the manner in which that plant grows. If the conditions are too extreme for a plant, then that plant cannot be as productive as other members of its species grown at less extreme temperatures. Such is the case of the pepper or tomato plant; if temperatures are too high for these plants, then the pollen these plants produce becomes inviable and these plants cannot successfully reproduce (Environmental Factors That……

What does risk and return mean to the average investor? In order to answer this question, investors must first look to themselves to determine the correct steps to take. One cannot call him or herself an investor without first measuring their risk tolerance as well as risk capacity. Risk tolerance represents how much a client is willing to withstand swings in the value of held assets as well as changes in general market conditions. One of the most common ways of measuring one’s risk tolerance is…

Problem Statement A case study was conducted by a manufacturing company, Ace Inc., that specializes in circuit boards used in security devices. The study aims to determine basic math competency of its production line workers. A random sample of 71 production line employees were chosen for the survey and the test data results were collected accordingly. The resulting data also includes whether each employee in the sample took a statistics course or not. Ace would like to examine this data in…

Lastly the mean, standard deviation and confidence interval were calculated for percentage increase of each type of music. As previously mentioned EEG is approximately ±50 μV, therefore data that was above 50μV was removed prior to carrying out the analysis (this includes ID 5, 7 and…

A sample revealed three bags of 56, two bags of 57, one bag of 55, and two bags of 58. To test the hypothesis that the mean candies per bag is 56, how many degrees of freedom are there? * 8 * 9 * 7 * 1 Which of the following is most appropriately displayed with a frequency table? * What percentage of people prefer Hunt's brand ketchup * The home location of the most valuable customers * The relationship between gender and job performance *…
