FCAT scores and poverty. In the state of Florida, elementary school performance is based on the average score obtained by students on a standardized exam, called the Florida Comprehensive Assessment Test (FCAT). An analysis of the link between FCAT scores and sociodemographic factors was published in the Journal of Educational and Behavioral Statistics (Spring 2004). Data on average math and reading FCAT scores of third graders, as well as the percentage of students below the poverty level, for a sample of 22 Florida elementary schools are summarized by the number given below. (x= percentage of students below poverty level, and y=math score ) n = 22 ??xi = 1292.7 ??yi = 3781.1 ??x2i =88668 ??yi2 =651612 ??xiyi =218292 (a) Propose a straight-line model relating math-score to percentage of students below poverty level. (b) Find the least-squares regression line fitting the model to the data. (c) Interpret the estimates for intercept and slope in the context of the problem. (d) Test whether the math score is negatively related to the percentage of students below the poverty level. (e) Construct a 99% confidence interval for the slope of the model, and interpret your result in the context of the problem.

Managing, Organizing & Negotiating for Value

Need an outline for a MGT course. Here are the specifics:

Select an actual current event that has ethical, legal and professional implications and has taken place in the context of a negotiation. An example might be the North Korean events on their atomic nuclear activities. Based on chapters 1 through 8 create an essay in the ESSAY FORMAT describing all of the relevant issues and aspects highlighting specific facts that you can attribute to the topics cover the negotiations of the issues. Be sure to cover examples of how your readings helped to resolve the final resolution or agreement. Please submit in APA compliant style.

Chapters 1-8 cover:

- the dynamics of negotiation (tensions between: creating and distributing value; empathy and assertiveness; and principals and agents

- the challenges of dispute resolution/deal making; and psychological and cultural barriers

- a problem-solving apporach (behind the table/across the table)

1. A candystore allows customers to select 3 different candies to be shipped. If there are a total of 10 varieties available, how many possible selections can be made?

2.The average cost of labor for car repairs for a chain of garages is $48.25. The standard deviation is $4.20. Assume normal distribution. If 20 stores are selected at random what is the probability that the mean of the sample labor cost will be between $46 and $48?

In reference to Problem 1, a random sample of 9 customers was taken. Mu=75K n=9 sigma=15K a What is the probability that the sample mean is below $70K? b. What proportion of the sample mean are above $80K? c. What percentage of the sample means are be between $70K and $80K? d. If the data was not distributed as a Normal Distribution, would you be able to answer the above questions?

Vertical Analysis of Income Statement

The following comparative income statement (in thousands of dollars) for the two recent fiscal years was adapted from the annual report of Calvin Motorsports, Inc., owner and operator of several major motor speedways, such as the Atlanta, Texas, and Las Vegas Motor Speedways.

a. Prepare a comparative income statement for these two years in vertical form, stating each item as a percent of revenues. Round to one decimal place. Enter all amounts as positive numbers.

Feedback

a. For each year, show each item as a percentage of total revenues.

b. While overall revenue decreased some between the two years, the overall mix of revenue sources did change somewhat. The NASCAR broadcasting revenue increased as a percent of total revenue by 3 percentage points, while the percent of admissions revenue to total revenue decreased by 2 percentage points. Overall, it appears that income from continuing operations has significantly improved because of aggressive cost cutting .

Here is a series of address references given as word addresses: 18, 19, 27, 16, 21, 0, 64, 48, 19, 11, 19, 22, 4, 27, 6, and 27. Assuming a direct-mapped cache with 16 one-word blocks that is initially empty, label each reference in the list as a hit or a miss and show the final contents of the cache.

Will improving customer service result in higher stock prices for the companies providing the better service? "When a company's satisfaction score has improved over the prior year's results and is above the national average (currently 75.7), studies show its shares have a good chance of outperforming the broad stock market in the long run." The following satisfaction scores of three companies for the 4th quarters of two previous years were obtained from the American Customer Satisfaction Index. Assume that the scores are based on a poll of 68 customers from each company. Because the polling has been done for several years, the standard deviation can be assumed to equal 8 points in each case.

Heraklion Co is a manufacturer of footballs and is a new audit client for your firm. You are an audit supervisor of Spinalonga & Co. and are currently preparing for the forthcoming interim and final audit for the year ending 31 October 2016. You are required to document and assess the sales system, recommend control improvements to deal with a specific fraud issue as well as undertake substantive testing of revenue.

Sales ordering, goods dispatched and invoicing

Heraklion Co sells footballs to a range of large and small sports equipment retailers in several countries. Sales are ma de through a network of sales staff employed by Heraklion Co, but new customer leads are generated through a third party company. Sales staff are responsible for assessing new customers' creditworthiness and proposing a credit limit which is then authorized by the sales director. The sales staff have monthly sales targets and are able to use their discretion in granting sales discounts up to a maximum of 10%. They then record any discount granted in the customer master data file.

The sales staff visit customer sites personally and orders are completed using a two-part pre-printed order form. One copy is left with the customer and the other copy is retained by the sales person. The sales order number is based on the sales person's own identification (ID) number.

The company markets itself on being able to dispatch all orders within three working days. Once the order is taken, the sales person emails the finance department and warehouse dispatch team with the customer ID and the sales order details and from this a pick list is generated. Sequentially numbered goods dispatched notes are completed and filed in the warehouse.

Sequentially numbered invoices are generated using the pick lists for quantities and the customer master data file for prices. Standard credit terms for customers are 30 days and on a monthly basis sales invoices which are over 90 days outstanding are notified to the relevant sales person to chase payment directly with the customer.

Required:

(a) Describe TWO methods for documenting the sales system, and for each explain ONE advantage and ONE disadvantage of using this method.      

(b) Identify and explain SEVEN deficiencies in the sales system of Heraklion Co and provide a recommendation to address each of these deficiencies.

Note: Prepare your answer using two columns headed Control deficiency and Control recommendation respectively.                                                                                                                                

(c)     Describe substantive procedures the auditor should perform to obtain sufficient and appropriate audit evidence in relation to Heraklion Co's revenue.
