Distribution Of Quantitative Dat Cups Of Coffee Essay

2. What reason did you give for why it is important to offer the model more than two cups (one with the milk added first and one with the milk added second)? Was your answer the same as Fisher's answer? Based on the essay, please describe Fisher's answer to this question.

Since in a normal distribution, the curve is symmetrical, skewness can affect the accuracy to which normal distribution can be applied to a data set. To determine how close the distribution of the weight of the AFL population is to being normal, the degree of skewness was found as a large degree of skewness would reduce the practicality of applying normal distribution to the data set.

The fictional story “Drinking Coffee Elsewhere,” by American author ZZ Packer, is about an African American college student that encounters many behavioral issues throughout her freshman year at Yale University. The main character of the story, Dina, is an insecure, immature, and selfish young adult who has gone through tough moments in her life. Dina is the narrator of the story; it is told through her eyes. After Dina mother’s death, her attitude gets worse and she tries to be isolated from everyone as much as she can. During Yale orientation, Dina introduced herself violently to the class, the dean of the college gets worried about her behavior, and she is assigned to attend counseling sessions with a psychologist. Dina then meets one of her poetry classmates accidently; after Heidi knocks at Dina’s door, they share time together, and become good friends. The main character sometimes may appear aggressive and uncaring do to the fact that she is dealing with self-identity problems. In the end, she suddenly appears upset and starts making many mistakes that end up costing her friendship. After losing the only friend she has, she wishes to go back and fix the mistakes she made.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

10. Identify whether these distributions are negatively skewed, positively skewed, or not skewed at all, and why.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

The data that I have is accurate because by looking at the histogram the graphs are perfectly skewed and, the data make sense, if I compare the data to the median and the IQR. And to find IQR subtract Quartile 3 from Quartile 1. The purpose of using mean value to see if the graph is symmetric or not but, in my case I do not have symmetrical graph or Boxplot, because it is sensitive to outliers. I choose to use the IQR instead of the standard deviation because it shows what is below the 1st quartile and above the 3rd quartile. To summarize, median and IQR are the best option because they resistant to outliers.

The following Histogram shows that the distribution is approximately symmetrical about the mean, or bell-shaped. Therefore, using the Empirical Rule, I concluded that 47.5% of the lbs. of milk produced per month fell between 2270.5 lbs. and 964.10 lbs. This accounts for a very large portion of the total milk produced; as 68% fell within 1 standard deviation of 653.20 of the mean, and 95% fell within 2 standard deviations of the mean.

Indicating the individual number 65 gives a 5 point range to the mean. It seems the median is the most accurate way to discribe the data set, as it uneffected by the outlier value.

5. For the following set of scores, compute the range, the unbiased and the biased standard deviations, and the variance. Do the exercise by hand.

Starbucks Corporation, generally known, as Starbucks Coffee is the leading retailer and a brand of world’s forte coffee in the world, with more than 15,000 retail locations in North America, Latin America, Europe, the Middle East and the Pacific Rim, wherever in this world where premium quality coffee is in demand. Starbucks is the largest coffeehouse company in the world ahead of UK rival Costa Coffee, with 20737 stores in 63 countries and territories, including 11910 in the United States, 1496 in China, 1442 in Canada, 1052 in Japan and 772 in the United Kingdom. The first Starbucks was open in 1970. The name was inspired from Herman Melville’s Moby Dick, a definitive American novel regarding the 19th century whaling industry. The nautical name matches seamlessly for a store that imports the world’s finest coffees to the cold thirsty people of Seattle. In May 1998, Starbucks have finally successfully entered the European market through its acquirement of 65 Coffee Company stores initially originated from Seattle in the UK. Both companies shared a common culture, focusing on a great commitment to customized coffee, similar company values and a mutual respect.

Enzymes are proteins that catalyze (speed up) biological reactions in an organism by lowering the activation energy of a reaction. They do this by either straining the bonds in a molecule so that is easier to break up or by placing separate molecules/elements close to each other so that bonds are formed. Enzyme activity is influenced by an array of different factors such as enzyme concentration, substrate concentration, temperature, pH and inhibitor concentration. All of these affect the rate of reactions of enzymes and some such as temperature, inhibitors and pH can under circumstances cause enzymes to become permanently affected. Catalase is an enzyme found in almost all organisms on earth exposed to Oxygen.

2. Which of the following values from Table 1 tells us about variability of the scores in a distribution?

Whereas, poverty shows a positive skewness value of .670 since its variables have numerous high values, which justifies the right skewness of the histogram.

Cameron’s Coffee was founded in 1978 by Jim Cameron and was later on purchased by Jim Kirkpatrick in 1999. The company specializes in ‘…premium flavored coffees, teas and powdered cocoa and cappuccino mixes (Petersen).’ Even though the coffee market is almost saturated, Cameron is looking to expand its operations not only in the United States, but in Europe and other continents. The company currently has a great advantage in this tight market, due to its dedication to quality. But in order to increase the probability for success, Cameron’s Coffee will need to expand its knowledge and involvement in technology and communication.
