1. In a series of projects I determined linear correlation coefficients between various explanatory and response variables. Rank projects thru 5 in order of the increasing strength of correlation.

2. What does r measure?

3. Given the following values of x and y, and using y as the response variable, find the regression line that best fits the data.

4. Estimate the y values associated with an x value of 13

Historical demand for a product is as follows:

April                60

May                 60

June                55

July                 75

August             80

September       75

(a.) Using a simple four-month moving average, calculate a forecast for October.

(b.) Using single exponential smoothing with alpha=0.3 and a September forecast =70, calculate a forecast for October.

(c.) Using simple linear regression, calculate the trend line (Yt) for the historical data. The X-axis scale is: April = 1, May = 2, and so forth. Y-axis is Demand from above.

Yt = a + bx =

(d.) Using the linear regression model above, what is a forecast for October?

Two flash resistance drums operated at 101.3 kPa are connected continuously.
You want to separate the hexaneooctane mixture. (Make the effective number two digits.

(a) fed feed with a zhexane of 0.3, 900 lbmol/hr, making V/F one-third flash at this time
How much is the liquid and vapor composition (yhexane,1, xhexane,1) of the hexane leaving the drum?
(b) (a) where the vapor disillate obtained through the problem is to be re-separated using the flash resistance drum;
All. The hexane composition (yhexane,2) of the projector stream leaving the second flash drum is to be 0.6
Calculate V2, L2, xhexane,2.

Consider an economy at the steady state according to the Solow Growth Model with a per capita production function  where n=0.04, d=0.08, and s=0.3. Suppose a change in the age profile of the population leads to a reduction of the savings rate to s=0.28. As a result,

A Relaxin receptor agonist drug (RRA01) for the acute heart failure treatment is developed by the Sunny Pharmaceutical Company. It is a publicly traded company. The reduction of cardiovascular death (mortality) was used as the end point (results of the research) for this investigation. The null hypothesis is “there is no difference in the cardiovascular mortality reduction between patients who received RRA01 (treatment group) and those who did not receive RRA01 (control group). Discuss the impact (on the company and/or on the patients) of the following two possible clinical trial results to the Sunny Pharmaceutical Company, staff of the company, and the patients. 1. p = 0.002 as the hypothesis test results 2. p = 0.3 as the hypothesis test results.

At a point in a stressed body, the principal stresses are 100 MN/m2
(tensile) and 60 MN/m2
(compressive). Determine the normal stress and
the shear stress on a plane inclined at 50degree
counter clockwise to the axis
of minor principal stress. Also, calculate the maximum shear stress at the
point and draw the Mohr’s stress circle to verify the answers.
If the yield strength and Poisson’s ratio of the material in the above case
is 240 MPa and 0.3 respectively, check whether the failure will occur or
not according to (a) Maximum principal strain theory and (b) Maximum
shear strain energy per unit volume theory. If failure does not occur,
calculate the Factor of Safety.

Create a supply and demand graph illustrating the scenario, the shock, and the predicted effects on wages and employment:

Scenario #1

Airbnb has housed over 150 million guests in over 65,000 cities since 2008. Do a bit of research on what Airbnb is and how cities and the hotel industry has been responding to it. Using standard supply and demand graphs from the course, model the labor market for hotel workers, pre-Airbnb, and show how Airbnb has likely affected the market.

Scenario #2

We all love to go to little, local ice cream shops. Many of these places hire teenagers over the summer to serve these delicious treats for us. Suppose that a new minimum wage bill comes online this summer, raising the minimum to $10/hour. Create two graphs: 1) model the market for these ice cream shop workers and how shop owners will likely respond to the minimum wage increase immediately after it happens; 2) model what would happen if a company starts using very cheap robot ice cream servers.

Scenario #3

Research and find specific examples of immigrants working as a) substitutes for U.S. workers and b) compliments to U.S. workers. Make sure you put the correct graph with each story.

Scenario #4

Many parts of the U.S. have a shortage of IT workers... not enough people are trained in these fields. Model the market for IT workers. What would happen if a new training program was targeted toward people in Appalachia who have a hard time finding work... the program trains this group to be IT technicians.

Scenario #5

You are looking at the labor market for young, childless males seeking work with low-paying employers (i.e. Wal-Mart). With a supply and demand graph, show the effects of expanding the EITC to these workers. Illustrate an initial equilibrium (before EITC), the shift due to the new EITC expansion, and point out the wage they get paid from the employer and the additional “pay” they get due to the EITC.

Q1

[The following information applies to the questions displayed below.]

At year-end December 31, Chan Company estimates its bad debts as 0.40% of its annual credit sales of $759,000. Chan records its Bad Debts Expense for that estimate. On the following February 1, Chan decides that the $380 account of P. Park is uncollectible and writes it off as a bad debt. On June 5, Park unexpectedly pays the amount previously written off.

Prepare Chan's journal entries to record the transactions of December 31, February 1, and June 5.

Q2

Liang Company began operations in Year 1. During its first two years, the company completed a number of transactions involving sales on credit, accounts receivable collections, and bad debts. These transactions are summarized as follows.

Year 1

1. Sold $1,351,400 of merchandise (that had cost $981,600) on credit, terms n/30.
2. Wrote off $20,400 of uncollectible accounts receivable.
3. Received $667,900 cash in payment of accounts receivable.
4. In adjusting the accounts on December 31, the company estimated that 1.10% of accounts receivable would be uncollectible.

Year 2

5. Sold $1,587,000 of merchandise (that had cost $1,251,700) on credit, terms n/30.
6. Wrote off $33,300 of uncollectible accounts receivable.
7. Received $1,374,300 cash in payment of accounts receivable.
8. In adjusting the accounts on December 31, the company estimated that 1.10% of accounts receivable would be uncollectible.

Required:
Prepare journal entries to record Liang’s Year 1 and Year 2 summarized transactions and its year-end adjustments to record bad debts expense. (The company uses the perpetual inventory system, and it applies the allowance method for its accounts receivable.) (Round your intermediate calculations to the nearest dollar.)

Prepare Chan's journal entries to record the transactions of December 31, February 1, and June 5.
