Analyzing Journal Article Results Researchers (Brian G. Feagan et al. “Erythropoietin with Iron Supplementation to Prevent Allogeneic Blood Transfusion in Total Hip Joint Arthroplasty,” Annals of Internal Medicine, Vol. 133, No. 11) wanted to determine whether epoetin alfa was effective in increasing the hemoglobin concentration in patients undergoing hip arthroplasty. A complete medical history and physical of the patients was performed for screening purposes and eligible patients were identified. The researchers used a computer-generated schedule to assign the patients to the high-dose epoetin group, low-dose epoetin group, or placebo group. The study was double-blind. Based on ANOVA, it was determined that there were significant differences in the increase in hemoglobin concentration in the three groups with a -value less than 0.001. The mean increase in hemoglobin in the high-dose epoetin group was 19.5 grams per liter (g/L), the mean increase in hemoglobin in the low-dose epoetin group was 17.2 g/L, and mean increase in hemoglobin in the placebo group was 1.2 g/L.

(a) Why do you think it was necessary to screen patients for eligibility?

(b) Why was a computer-generated schedule used to assign patients to the various treatment groups?

(c) What does it mean for a study to be double-blind? Why do you think the researchers desired a double-blind study?

(d) Interpret the reported P-value.

Case Study

Feeling Lucky? Well, Are You?

In fiscal year (FY) 2013–2014 (July 2013–June 2014), the Florida Lottery generated $5.37 billion in total sales. Over that period, the state spent $37.5 million on advertising to promote its various games. Rand Advertising is interested in gaining access to this lucrative market. You are assigned the task of preparing a report on the lottery sales structure for three of Florida’s online (nonscratch-off ticket) games: Fantasy 5, Lucky Money, and Lotto. Your findings will become part of a proposal by Rand to the Florida Lottery.
In Fantasy 5, a player picks five numbers from 1 to 36, at $1 per play. Drawings are held seven days a week. If there is no jackpot winner for a drawing, the money allocated for the top prize rolls down to the next prize tier (4 of 5).
The Lucky Money game costs $1 per ticket. Players pick four numbers from 1 to 47 and one Lucky Money number from 1 to 22. Drawings are held on Tuesdays and Fridays. If there is no jackpot winner for a drawing, the money allocated for the top prize rolls over to the next drawing, adding to the total of the next jackpot. The prize structures for both games is as shown.

In Lotto, players pick six numbers from 1 to 53, at $1 per play. Drawings are held on Wednesdays and Saturdays. If there is no jackpot winner, the top prize is rolled over to the next drawing. It is difficult to win the Lotto jackpot, so there are numerous jackpot rollovers. Rollovers make it difficult to determine an estimated prize payout per winner. However, the odds structure is shown in the table at the top of the next column.

To conduct your study, you have obtained the sales figures for each of the three games by district sales office for one week. These data are as follows:

Are the numbers of tickets sold for each lottery game and sales district independent? Construct a bar graph that represents the conditional distribution of game by sales district. Does this graphical evidence support your conclusion regarding the relationship between the type of game and the sales district? Explain.
Additionally, you are interested in the daily sales structure for the various districts. The following are the numbers of tickets sold each day for a randomly selected week for the three games in District 1.

Does the evidence suggest that the proportion of Fantasy 5 sales is the same for each day of the week? Perform a similar test for Lucky Money and Lotto.
Write a report detailing your assumptions, analyses, findings, and conclusions.

A Mexican firm employs unskilled, semiskilled, and skilled labor in a cost-minimizing mix at its manufacturing plant. The marginal product of unskilled labor is considerably lower than semiskilled and skilled labor, but the equilibrium wage for unskilled labor is only 300 pesos per day. The government passes a law that mandates a minimum wage of 400 pesos per day. Equilibrium wages for semiskilled and skilled labor exceed this minimum wage and therefore are not affected by the new law. The firm will most likely respond to the imposition of the minimum wage law by:

A. employing more unskilled workers at its plant. B. employing fewer unskilled workers at its plant. C. keeping the mix of unskilled, semiskilled, and skilled workers the same.

Prepare your own five-year career development plan about ‘What do you intend to do professionally in the next 5 years (1st year, 2nd year, 3rd year, 4th & 5th year)’? Your plan must be presented in time-line format (This can be done using MS Project and multiple other software). Your plan will also be assessed on the basis of how creative your timeline is. Simple timelines (a simple table of one made using word) will be marked down. Be very specific with your timeline, provide dates for when you will achieve different things mentioned in your timeline. For instance, if you mention in your timeline, you will attempt an test provide a DATE of when you will attempt that test. Also include the COSTS associated with completing different activities. Your career plan must address and consider the following items:

  1. What are your career objectives? What position, field or industry do you want to work in/for? (To be answered in introductory paragraph – Max 1 page)
    • Which province in Canada and why? (This needs to be supported with job market analysis such as employment options, field attractiveness- current job openings within your field, income potential/salary rates across different provinces– I want to see a lot of statistics in here – Don’t make this section descriptive – use graphs, pie-charts, salary benchmarking tables from federal and provincial reliable sources)
      2. If you in intend to work for an organization, what are the possible promotional opportunities for career growth and what senior level position do you wish to obtain? How long will it take for you to obtain your next promotion within your field? What certificate will be needed for promotion? how many years of experience will be required for the promotion? (Again, maximum one page in writing and also included these promotions in your timeline)
