1. In the following observational studies, describe changes that could be made to the data collection process that would result in an experiment rather than an observation study. Also, offer suggestions about unseen biases or lurking variables that my be present in the studies as they are describe here.

a. In a sample of 50 members of a local health club you find that 12 of these members meet weekly with a physical fitness trainer and that the average body mass index (BMI) of these 12 members is less than the average BMI of the other 38 club members in your sample.

b. In a sample of 12 bank tellers at a local branch office, the 7 tellers who have completed the advanced training program offered by the bank have a lower average error rate in the processing of transactions than the remaining 5 tellers.

In the month of July, Adam’s oil performed 4,000 oil changes at a price of $20. During the month, fixed costs were $18,000 and variable costs were 40% of sales. Show your math work for all parts of this problem.

1a. First do a CVP income statement (show the percents, the per unit costs, and the totals):

2. Determine the contribution margin in total dollars, per unit, and as a ratio. (Take the numbers from the income statement above, but also show the formulas you can use to compute all these amounts.)

CM total $______________    CM per unit $__________    CM ratio ___________%

3. Compute the breakeven point in dollars and units.

4. Compute the margin of safety in dollars and as a ratio.

e.          How many units do they have to sell to earn a net income of $12,000?

6. What is the breakeven sales units if Adam’s charges $18 for an oil change and variable costs are 60% of sales?

Estimate the firm's net source and use of cash from the following changes in assets and liabilities:1) Inventories decreases by $55; 2) Accounts Receivable increases by $15; 3)Accounts Payable increases by $30; 4)Short term debt decreases by $8

1.) Describe the changes in production requirements and the location of production that take place over the three phases of the product cycle.

1. Identify 3 major changes in the way people are consuming food, and their impact on McDonalds?
2. Is McDonalds overspending, and squeezing its franchise unnecessarily?
3. Why is McDonalds' share price going

We’ve discussed several different changes that are happening to the population of the US. Thinking about the niche market segments we’ve also discussed, pick a niche market, define that market, and discuss how agencies in that industry can be successful based on those changes.

Changing Demographics to Discuss

                The aging of the largest segment of the population, the Baby Boomers

The change in ethnic demographics and increase in minority participation in leisure/recreation/tourism

                The prevalence of dual-earner families/single-parent families

                The steady increase of television use

Must cover all 4 changing demographic sections, focusing on 1 niche market (may use up to 2 markets, if linked).

In making a changes to a method in an accounting practice/method, why do you think it would be import to compare the reports(FIFO &LIFO) using both to give the reader the results using both methods. IE in your inventory change, what would be COS using both

Please calculate the COGS, changes of Inventory, Revenue and all Sales and Inventory was purchased on account. Use the FIFO method.

Given the price elasticities and price changes for the following products A–E in the table below, show how much the quantity will change (indicating an increase or decrease) and what effect this will have on total revenue (indicating an increase or decrease). Round your answers to 1 decimal place.
