Visit the NASDAQ historical prices weblink. First, set the date range to be for exactly 1 year ending on the Monday that this course started. For example, if the current term started on April 1, 2018, then use April 1, 2017 – March 31, 2018. (Do NOT use these dates. Use the dates that match up with the current term.) My class started 14 January 2019. Do this by clicking on the blue dates after “Time Period”. Next, click the “Apply” button. Next, click the link on the right side of the page that says “Download Data” to save the file to your computer. This project will only use the Close values. Assume that the closing prices of the stock form a normally distributed data set. This means that you need to use Excel to find the mean and standard deviation. Then, use those numbers and the methods you learned in sections 6.1-6.3 of the course textbook for normal distributions to answer the questions. Do NOT count the number of data points. Complete this portion of the assignment within a single Excel file. Show your work or explain how you obtained each of your answers. Answers with no work and no explanation will receive no credit. 1. a) Submit a copy of your dataset along with a file that contains your answers to all of the following questions. b) What the mean and Standard Deviation (SD) of the Close column in your data set? c) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points) 2. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at more than $950? (5 points) 3. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $50 of the mean for that year? (between 50 below and 50 above the mean) (5 points) 4. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than $800 per share. Would this be considered unusal? Use the definition of unusual from the course textbook that is measured as a number of standard deviations (5 points) 5. At what prices would Google have to close in order for it to be considered statistically unusual? You will have a low and high value. Use the definition of unusual from the course textbook that is measured as a number of standard deviations. (5 points) 6. What are Quartile 1, Quartile 2, and Quartile 3 in this data set? Use Excel to find these values. This is the only question that you must answer without using anything about the normal distribution. (5 points) 7. Is the normality assumption that was made at the beginning valid? Why or why not? Hint: Does this distribution have the properties of a normal distribution as described in the course textbook? Real data sets are never perfect, however, it should be close. One option would be to construct a histogram like you did in Project 1 to see if it has the right shape. Something in the range of 10 to 12 classes is a good number. (5 points)

Seacrest Company uses a process costing system. The company manufactures a product that is processed in two departments: A and B. As work is completed, it is transferred out. All inputs are added uniformly in Department A. The following summarizes the production activity and costs for November:

1(c) Using the weighted average method, prepare a calculation of unit costs for Department A. Refer to the list of Amount Descriptions for the exact wording of text items within your schedule. Round to two decimal places. (Note: Be sure to enter the unit cost below the table.)

What is the unit cost?

1(d) Using the weighted average method, calculate the cost of EWIP and cost of goods transferred out for Department A.

Cost of EWIP:$ ____

Cost of goods transferred out: $_____

1(e) Using the weighted average method, prepare a cost reconciliation for Department A. Refer to the list of Amount Descriptions for the exact wording of text items within your schedule.

Note: Costs to account for and Costs accounted for will differ due to rounding.

2. CONCEPTUAL CONNECTION: (a) Prepare journal entries on Nov. 30 that show the flow of manufacturing costs for Department A. Use a conversion cost control account for conversion costs. Refer to the Chart of Accounts for the exact wording of account titles. (Note: Be sure to complete part (b) below the journal.)

GENERAL JOURNAL

1. The U.S. Food and Drug Administration (FDA) requires nutrition labeling for most foods. Under FDA regulations, manufacturers are required to list the amounts of certain nutrients in their foods, such as calories, sugar, fat, and carbohydrates. This nutritional information is displayed on the food’s package.

1. Find the equation of a regression line for each pair of variables

1. Calories, sugar

2. Calories, carbohydrates

2. Use the results of the previous exercise to predict each value.

1. The sugar content of one cup of cereal that has 120 calories.

2. The carbohydrate content of one cup of cereal that has 120 calories.

3. Find the multiple regression equations of each form

1. C=β0+ β1S+ β2F+ β3R

2. C=a0+a1S+a2R

4. Use the results from part iii) above, to predict the calories in 1 cup of cereal that has 7 grams of sugar, 0.5 grams of fat, and 31 grams of carbohydrates.

Calculate the number of nonzeros in the Jacobian matrix and the number of nonzeros in the bus admittance matrix for this system . Why is a slack bus needed in the power flow analysis ?

Michael Porter suggests seven ways in which companies can incorporate E-marketing into marketing and sales activities (Section 11-2). Choose an organization that has an online presence and provide real-world examples for two of these methods. Explain how/why these methods are appropriate for your chosen organization.

The following is a stem and leaf chart of the head circumferences (in centimeters) of two-month old female babies:

Is there enough evidence to indicate that the typical two-month old female baby has a head circumference larger than 39.0cm, with a 0.05 significance level? Justify your answer. Use s = 1.6395 cm.

5. Costs in the short run versus in the long run Ike’s Bikes is a major manufacturer of bicycles. Currently, the company produces bikes using only one factory. However, it is considering expanding production to two or even three factories. The following table shows the company’s short-run average total cost (SRATC) each month for various levels of production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.) Number of Factories Average Total Cost (Dollars per bike) Q = 50 Q = 100 Q = 150 Q = 200 Q = 250 Q = 300 1 180 100 80 120 200 360 2 270 150 80 80 150 270 3 360 200 120 80 100 180 Suppose Ike’s Bikes is currently producing 50 bikes per month in its only factory. Its short-run average total cost is $ per bike. Suppose Ike’s Bikes is expecting to produce 50 bikes per month for several years. In this case, in the long run, it would choose to produce bikes using . On the following graph, plot the three SRATC curves for Ike’s Bikes from the previous table. Specifically, use the green points (triangle symbol) to plot its SRATC curve if it operates one factory ( SRATC1 ); use the purple points (diamond symbol) to plot its SRATC curve if it operates two factories ( SRATC2 ); and use the orange points (square symbol) to plot its SRATC curve if it operates three factories ( SRATC3 ). Finally, plot the long-run average total cost (LRATC) curve for Ike’s Bikes using the blue points (circle symbol). Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically. SRATC 1 SRATC 2 SRATC 3 LRATC 0 50 100 150 200 250 300 350 400 360 320 280 240 200 160 120 80 40 0 AVERAGE TOTAL COST (Dollars per bike) QUANTITY OF OUTPUT (Bikes) In the following table, indicate whether the long-run average cost curve exhibits economies of scale, constant returns to scale, or diseconomies of scale for each range of bike production.
