Question

1. Basic Business Math: a. Suppose that $126,000 is to be allocated for advertising, research, and investment in the ratio 10:4:2. How much money will be allocated for each? b. Electric Depot sells boxes of high efficiency light bulbs ($8 box) and switch plates ($10 each). In June, total sales were $42000. Customers bought 5 times as many boxes of light bulbs as switch plates. How many of each did Electric Depot sell? 2. Create an Excel spreadsheet that can be used to calculate your grade in this class. The spreadsheet should include the weights of each graded assignment, your grade in each assignment, and your final grade. To use this for your benefit you may want to design it so that it can be used to calculate your interim grade before you have all the grades. Use a new sheet called "Grade Calculator" in the same Excel file that you are submitting for this assignment. After this week you will receive the solution from your professor and you will be able to use your solution or our solution for future classes. 3. A quality characteristic of interest for a tea-bag-filling process is the weight of the tea in the individual bags. If the bags are under filled, two problems arise. First, customers may not be able to brew the tea to be as strong as they wish. Second, the company may be in violation of the truth-in-labeling laws. In this example, the label weight on the package indicates that, on average, there are 3.40 grams of tea in a bag. If the average amount of tea in a bag exceeds the label weight, the company is giving away product. Getting an exact amount of tea in a bag is problematic because of variation in the temperature and humidity inside the factory, differences in the density of the tea, and the extremely fast filling operation of the machine (approximately 215 bags a minute). The following table provides the weight in grams of a sample of 50 bags produced in one hour by a single machine: 2.75 3.7 3.42 3.4 3.53 2.54 3.54 3.45 3.52 4.2 3.57 3.4 3.83 2.54 3.55 2.62 3.66 3.46 2.64 3.51 3.67 3.4 3.47 3.61 2.53 3.32 2.67 3.29 3.49 3.55 4.78 3.57 3.42 3.58 3.68 3.5 3.32 3.5 3.53 2.58 3.75 3.45 3.44 3.25 3.56 3.63 3.5 2.57 3.67 3.36 a. Compute the arithmetic mean and median. b. Compute the first quartile and third quartile. c. Compute the range, interquartile range, variance, standard deviation, and coefficient of variation. d. Interpret the measures of central tendency within the context of this problem. Why should the company producing the tea bags be concerned about the central tendency?,Hi, i am specifically looking for assistance on how to solve these problems! I have been unable to find assistance from the text book or online workbook. Thank you,this was helpful... i had one more question that didn't get attached... A well known grape juice production company maintains records concerning the number of unacceptable containers of grape juice obtained from the filling and capping machines. Based on past data, the probability that a container came from machine I and was nonconforming is 0.03 and the probability that a container came from machine II and was nonconforming is 0.07. These probabilities represent the probability of one container out of the total sample having the specified characteristics. Half the containers are filled on machine I and the other half are filled on machine II. If a filled container of juice is selected at random, what is the probability that it is a nonconforming container? If a filled container of juice is selected at random, what is the probability that it was filled on machine II? If a filled container of juice is selected at random, what is the probability that it was filled on machine I and is a conforming container?
