This is an assignment in my business statistics class (FINA 220)This assignment consists of solving 4 problems from the textbook (Statistical Techniques in
Business and Economics, 16
th Edition, McGraw-Hill), two from chapter 2 and two from chapter 3. Excel data files are provided below for each of the problem. When you solve the 4 problems, please copy the data into 4 tabs of one Worksheet before you start. Do not keep it in 4 files.Here are the problems:2.30) The weekly amounts spent on groceries for a sample of 45 households is provided in the attached file. a) How many classes would you recommend for grouping the data?b) What class interval would you suggest?c) What would you recommend as the lower limit of the first class?d) Organize the data into a frequency distribution.e) Plot the distribution using a bar chart in Excel.2.43) Merill Lynch recently completed a study regarding the size of online investment portfolios (stocks, bonds, mutual funds, and certificates of deposit) for a sample of clients in the 40 up to 50 years old age group. The value of all investments in thousands of dollars for the 70 participants in the study is provided in the attached file.a) Organize the data into frequency distribution. How many classes would you suggest ? What value would you suggest for a class interval?b) Draw a histogram. Inerpret your results.c) What is the mean, the variance, and the standard deviation of the data?3.65 A sample of households that subscribe to United Bell Company for landline phone service revealed the following number of calls received per household last week (see attached data file for the numbers).

1. A projectile is fired upward from the ground with an initial velocity of 300 feet per second. Neglecting air resistance, the height of the projectile at any time t can be described by the polynomial function P(t) = -16t2 + 300t a. Find the height of the projectile when t = 1 second. b. Find the height of the projectile when t = 5 seconds.c. How long will it be until the object hits the ground? 2. A board has length (3x4 + 6x2 – 18) meters and width of 2x + 1 meters. The board is cut into three pieces of the same lengtha. Find the length of each piece. b. Find the area of each piece.c. Find the area of board before it is cut. d. How is the area of each piece of the board related to the area of the board before it is cut? 3. A cubic equation has zeros at -2, 1, and 3. a. Write an equation for a polynomial function that meets the given conditions. b. Draw the graph of a polynomial function that meets the given conditions. 4. Alice was having a conversation with her friend Trina, who had a discovery to share: Pick any two integers. Look at the sum of their squares, the differences of their squares, and twice the product of the two integers you chose. Those three number are the sides of a triangle. a. Write an equation that models this conjecture using the variables x and y. b. Investigate this conjecture for at least three pairs of integers. Does her trick appear to work in all cases, or only in some cases? Explain. c. Use Trina's trick to find an example of a right triangle in which all of the sides have integer length, all three sides are longer than 100 units, and the three side lengths do not have common factors.d. If Trina's conjecture is true, use the equation found in part a. to prove the conjecture. If it is not true, modify it so it is a true statement, and prove the statement.

Strayer University Wk 4 Transforming Data Into Information Woodmill Company Report
Week 4 Assignment - Case Study: Transforming Data Into Information
Overview
The Woodmill Company makes windows and door trim products. The first step in the process is to rip dimension (2 × 8,2 × 10, etc.) lumber into narrower pieces. Currently, the company uses a manual process in which an experienced operator quickly looks at a board and determines what rip widths to use. The decision is based on the knots and defects in the wood.
A company in Oregon has developed an optical scanner that can be used to determine the rip widths. The scanner is programmed to recognize defects and to determine rip widths that will optimize the value of the board. A test run of 100 boards was put through the scanner and the rip widths were identified. However, the boards were not actually ripped. A lumber grader determined the resulting values for each of the 100 boards, assuming that the rips determined by the scanner had been made. Next, the same 100 boards were manually ripped using the normal process. The grader then determined the value for each board after the manual rip process was completed. The resulting data, in the file, Woodmill Data, consists of manual rip values and scanner rip values for each of the 100 boards.
Instructions
You are a process manager at the Woodmill Company tasked with determining if an optical scanner would be beneficial. Write a 4–5 page report to your supervisor (including a cover page and a Source List page) in which you:
Summarize the Woodmill Company’s problem of ripping dimension lumber into narrower pieces.
Develop a frequency distribution for the board values for the scanner and the manual process.
Generate appropriate descriptive statistics for both manual and scanner values.
Analyze the frequency distribution and descriptive statistics for both manual and scanner processes. Use Excel to create your charts.
Determine which process generates more values that were more than 2 standard deviations from the mean (manual or scanner).
Evaluate which process has less relative variability, using frequency distribution and descriptive statistics.
Recommend whether the optical scanner is the best option for the company.
