1-2. Data are based on numeric measurements of some variable, either from a data set comprising an entire population of interest, or else obtained from only a sample (subset) of the full population. Instead of doing the measurements ourselves, we may sometimes obtain data from previous results in published form.

1-3. The weakest is the Nominal Scale, in which categories of data are grouped by qualitative differences and assigned numbers simply as labels, not usable in numeric comparisons. Next in strength is the Ordinal Scale: data are ordered (ranked) according to relative size or quality, but the numbers themselves don't imply specific numeric relationships. Stronger than this is the Interval Scale: the ordered data points have meaningful distances between any two of them, measured in units. Finally is the Ratio Scale, which is like an Interval Scale but where the ratio of any two specific data values is also measured in units and has meaning in comparing values.

1-6. A qualitative variable describes different categories or qualities of the members of a data set, which have no numeric relationships to each other, even when the categories happen to be coded as numbers for convenience. A quantitative variable gives numerically meaningful information, in terms of ranking, differences, or ratios…...

...Question 1 # sold | P(x) | 0 | 0.1 | 1 | 0.11 | 2 | 0.2 | 3 | 0.23 | 4 | 0.3 | 5 | 0.06 | Question 2: The average rate of occurrence of accidents was 8.15 per week. A) during that time, what is the probability of getting less than 3 accidents a week? Use poisson for this question. Since it is less that 3 accidents, x = 0,1,2 (Px=o) = [(8.15^0) (e^8.15)] / 0! = 0.00288735. (Px=1) = [(8.15^1) (e^8.15)] / 1! = 0.002353193. (Px=2) = [(8.15^2) (e^8.15)] / 2! = 0.009589362. Add all these results together, and p(x<3) is 0.01223119. B) The probability if an accident on the road is 0.295. Out of 10 reportable accidents, what is the probability that 2 occurred on the road? Use Binomial for this. Since it is exactly 2, we need to find P(x=2). Use the binomial formula, n = 10, x = 2, p = 0.295, and q is 0.705. = 10!/2!(10-2)! * 0.205 ^2 * q^ 10-2. Answer is 0.23898436. Question 3: 15% of drivers have a probationary license and 85% have a regular license. In a given year, 10% of drivers with probationary licenses are involved in an accident. 2.5% of regular drivers are involved in an accident. For this question it is better to draw a tree diagram. Question 4: Mean values for income for men are 100K, for woman, 80K. SD deviations of 20K and 15K respectively. Variables are normally distributed and independent. Calculate the 95th percentile, for men income. 95th p = 0.95. In the zscore table, we find a value of 1.64. Us e the formula for z-score (population) : ......

...Appendix A Pricing Products and Services Solutions to Questions A-1 In cost-plus pricing, prices are set by adding a markup to a product’s cost. The markup is usually a percentage. A-2 The price elasticity of demand measures the degree to which a change in price affects unit sales. The unit sales of a product with inelastic demand are relatively insensitive to the price charged for the product. In contrast, the unit sales of a product with elastic demand are sensitive to the price charged for the product. A-3 The profit-maximizing price should depend only on the variable (marginal) cost per unit and on the price elasticity of demand. Fixed costs do not enter into the pricing decision. Fixed costs are relevant in a decision of whether to offer a product or service at all, but are not relevant in deciding what to charge for the product or service once the decision to offer it has been made. Because price affects unit sales, total variable costs are affected by the pricing decision and therefore are relevant. A-4 The markup over variable cost depends on the price elasticity of demand. A product whose demand is elastic should have a lower markup over cost than a product whose demand is inelastic. If demand for a product is inelastic, the price can be increased without as drastically reducing unit sales. A-5 The markup in the absorption costing approach to pricing is supposed to cover selling and administrative expenses as well as providing for an adequate......

...Here is one possible solution to Assignment 1. Following the solution, I have written some important general comments on programming issues and submitting assignments. Program Description: This program will accept the lengths and widths of four rooms from the user, then use this data to compute the total area. The result will be displayed for the user. Analysis: Inputs: There are eight inputs: the lengths and widths of each room. Outputs: There is one output: the total area. Obtaining the Outputs from the Inputs: For each room, we have to multiply the length by the width to get the area. Then the four room areas are added to get the total area. Mathematical Formulas: Area of a rectangle: Area = Length * Width. Total area of a complex figure: add the areas of the parts. Variables table: Name Data Type Usage Length1 Float Length of room 1 in feet Width1 Float Width of room 1 in feet. Length2 Float Length of room 2 in feet Width2 Float Width of room 2 in feet.

...Lindsey Pierce Exercise 11 HLT-362V January 14, 2016 Using Statistics to Describe a Study Sample 1. What demographic variables were measured at least at the interval level of measurement? Answer: The demographic variables that are measured at the interval level are: age, income, length of labor, return to work, and number of hours working per week. 2. What statistics were used to describe the length of labor in this study? Were these appropriate? Answer: The statistics used to describe the length of labor in this study were mean and standard deviation. These were appropriate as they both can be calculated at the interval level of measurement. 3. What other statistic could have been used to describe the length of labor? Provide a rationale for you answer. Answer: The median could be used though the mean and standard deviation are closer for both of the groups. 4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide rationale for your answer. Answer: Yes, the standard deviation measured the average deviation values of the mean. So, the difference between the two groups would be 0.48 hours which in this case is less than 30 minutes so the mean had a difference of 1.84 hours. 5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer. Answer: Yes, both of the groups were similar in their type of feeding though the difference......

...CHAPTER 1 Introduction to Financial Statements ANSWERS TO QUESTIONS 1. The three basic forms of business organizations are (1) sole proprietorship, (2) partnership, and (3) corporation. 2. Advantages of a corporation are limited liability (stockholders not being personally liable for corporate debts), easy transferability of ownership, and easier to raise funds. Disadvantages of a corporation are increased taxation and government regulations. 3. Proprietorships and partnerships receive favorable tax treatment compared to corporations and are easier to form than corporations. They are also owner controlled. Disadvantages of proprietorships and partnerships are unlimited liability (proprietors/partners are personally liable for all debts) and difficulty in obtaining financing compared to corporations. 4. Yes. A person cannot earn a living, spend money, buy on credit, make an investment, or pay taxes without receiving, using, or dispensing financial information. Accounting provides financial information to interested users through the preparation and distribution of financial statements. 5. Internal users are managers who plan, organize, and run a business. To assist management, accounting provides timely internal reports. Examples include financial comparisons of operating alternatives, projections of income from new sales campaigns, forecasts of cash needs for the next year, and financial statements. 6. External users are those outside the......
