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…

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…

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…

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……

1. QUESTION: Class, what does the correlation coefficients of -1, +1, and 0 tells you about the relationship between the two variables? It depends on the method one uses, but the Pearson correlation coefficient is the most widely used. Values in the form of numbers show the direction and how strong the relationship is between two different variables. These can range from -1.00 up to +1.00. If it is positive it is a direct relationship. For example, if one increases the other will also increase…

was 7.67 as shown in figure 1. The standard deviation was 4.84. Trial numbers increased sharply when Stentor were placed into warmer water. In the first trial of 20ºC water, Stentor traveled 24 lines in one minute. Stentor traveled 28 lines in the second trial and 27 lines in the final trial of 20ºC water results are listed in table 1. The range for the 20ºC water was a difference of 3 lines and the mean was 26.3 lines also shown in table 1. The standard deviation for 20ºC water was 2.08. The…

both downward and upward trend pattern of nail cuticle-biting behaviors. The mean value of the baseline is 6 and the standard deviation is 1.26. The first intervention phase data a downward trend pattern can be observed, which signifies a decrease in the amount of nail cuticle biting behaviors performed. The mean value of the first intervention data is 2.16, with a standard deviation of 1.47. Once the HRT intervention was applied, the targeted nail cuticle -biting…

A gap-filling method was developed based on the Principal Component Analysis (PCA) method. PCA is a widely used dimensionality reduction method to find a new set of variables as linear combinations of original variables, capturing most of the observed variance in the original data (Storch and Zwiers, 2002). It has been used in various climate studies for decomposing dominant mode (Storch and Zwiers, 2002) and time-series gap-filling (Beckers and Rixen, 2003; Kondrashov et al., 2014). The…

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…

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 *…
