AMS communicates with customers who subscribe to cable television services through a special secured email system that sends messages about service changes, new features, and billing information to in-home digital set-top boxes for later display. To enhance customer service, the operations department established the business objective of reducing the amount of time to fully update each subscriber's set of messages. The department selected two candidates messaging systems and conducted an experiment in which 30 randomly chosen cable subscribers were assigned one of the two systems (15 assigned to each system). Update times were measured, and the results are organized in Table AMS 10.1 on page 388 (and stored in AMS 10-1).

EX. 1. Analyze the data in Table AMS 10.1 and write a report to the computer operations department that indicates your findings. Include an appendex in which you discuss the reason you selected a particular statistical test to compare the two independent groups of callers. Email Interface 1 Email Interface 2 4.13, 3.75, 3.93, 3.74, 3.36, 3.85, 3.26, 3.73, 4.06, 3.33, 3.96, 3.57, 3.13, 3.68, 3.63 3.71, 3.89, 4.22, 4.57, 4.24, 3.9, 4.09, 4.05, 4.07, 3.8, 4.36, 4.38, 3.49, 3.57, 4.74

EX 2. Suppose that instead of the research design described in the case, there were only 15 subscribers sampled, and the update process for each subscriber email was measured for each of the two messaging systems. Suppose that the results were organized in Table AMS 10.1- making each row in the table a pair of values for an individual subscriber. Using these suppositions, reanalyze the table AMS 10.1 data and write a report for presentation to the team that indicates your findings

A. Calculate appropriate ratios under the following listed categories:

1. Profitability Ratios

2. Liquidity Ratios

3. Efficiency Ratios

4. Gearing Ratios and Investor Ratios

A restaurant in London is in its first 12 months of business. The year was somewhat successful, with the owner averaging $1,000 net profit per month after all deductions and expenses. However, he is unhappy with the amount of time it has been taking staff to provide customer service (measured from the time the customer enters to the moment they leave with their food). The restaurant design team was convinced that the restaurant’s design would allow for an average delivery time of approximately 7 minutes. As the owner was concerned they might not be hitting the mark, the design team asked a consultant to conduct a small study to examine customer service delivery time. A sample of 20 restaurant customers was selected, and the delivery time was recorded to the nearest minute.

Minutes:

5, 6, 7, 10, 6, 4, 7, 6, 8, 5, 11, 8, 7, 9, 7, 8, 8, 7, 9, 3

(A) Does the empirical evidence suggest that it takes significantly longer on average to service customers than the 7 minutes anticipated by the design team? Construct a 90% confidence interval a estimate of the average customer service delivery time at this restaurant. Interpret the meaning of the interval. Ensure that the interpretation of the results addresses the owner’s concerns. Please use clear, easy-to-understand, non-technical language.

(B) How would the consultant explain what they did in (A) to the restaurant’s design team - if they do not understand technical statistical language, and you have to explain in an easy-to-understand way?

Congratulations! You have just been appointed to a commission studying wage discrimination against women. Again, you have been pushed from the frying pan into the fire, as this is a sensitive topic. It is your role to give the background report to the commission, who will subsequently make some recommendations for anti-discrimination policy.

1) There are several theoretical models of labour market discrimination that seek to explain why men and women with equal productivity levels may not be paid the same. Briefly describe in intuitive terms the demand-side approach, the supply-side approach (the crowding hypothesis), and the non-competitive approach involving barriers to mobility.

2) It is true that, on average, women spend less time in the labour market gaining experience, on-the-job training, and other forms of human capital than men do, which is often tied to childbearing responsibilities. Some apologists claim that lower pay for women might be justified, as employers have less of an incentive to invest in workers with higher turnover. On the other hand, this line of reasoning has been countered by some analysts. What is the nature of the critique of those who disagree with the apologists? (An apologist would say that the pay differentials are justifiable based on productivity and that there is no direct discrimination against women.)

3) Empirical research on male-female earnings differentials is required to assess the validity of the models. The extent of the wage discrimination is typically measured by the so-called Oaxaca decomposition effect. Without getting into the technical details of this equation, explain the general idea of the procedure. You should describe the major elements. No graph is necessary.

Metallic element are _____ (conductors or non-conductors), because ________. Nonmetallic elements are generally ____ (conductors or non-conductors). Pure solid ionic compounds are ______ (conductors or non-conductors), because_____, but molten ionic compounds are ______ (conductors or non-conductors), because _______.

Pure molecular compounds are generally _____ (conductors or non-conductors). A concentrated aqueous solution of a strong acid such as HCl is a _____ (conductor or non-conductor), because _____. As the concentration of the HCl solution decreases, the conductance ____ (decreases or increases), because _____. Mixtures of metals(also called alloys) are _____ (conductors or non-conductors), because ______.

QUESTION 1
The objective of IFRS 5 Non-current Assets Held for Sale and Discontinued Operations specifies, amongst other things, accounting for and presentation and disclosure of discontinued operations. Radar’s sole activity is the operation of hotels all over the world. After a period of declining profitability, Radar’s directors made the following decisions during the year ended 31 December 2019:
• it disposed of all of its hotels in country A
• it refurbished all of its hotels in country B in order to target the holiday and tourism market. The previous target market in country B had been aimed at business clients.
Required:
(a) Define a discontinued operation and explain why the disclosure of such information is important to users of financial statements.
(b) Treating the two decisions separately, explain whether they meet the criteria for being classified as discontinued operations in the financial statements for the year ended 31 December 2018.

At December 31, 2015, the followings require inclusion in a company’s financial statements: On December 1, 2015 the company made a loan of $12,000 to an employee, repayable on December 1, 2018, charging interest at 2% per year. On the due date, she repaid the loan and paid the whole of the interest due on the loan to that date. The company paid an annual insurance premium of $9,000 in 2015, good for coverage through to July 31, 2016. On January 31, 2016, the company received rent from a tenant of $6,000 covering the six months to January 31, 2016.
