Older people often have a hard time finding work. AARP reported on the number of weeks it takes a worker aged 55 plus to find a

job. The data on number of weeks spent searching for a job are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions. Open spreadsheet a. Provide a point estimate of the population mean number of weeks it takes a worker aged 55 plus to find a job. weeks (to whole number) b. At 95% confidence, what is the margin of error? Please round the answer to four decimal places. (to 4 decimals) c. What is the 95% confidence interval estimate of the mean? Please round the answer to two decimal places. ( , ) weeks

Answer:

See attached picture to view the graph

Step-by-step explanation:

Start by analyzing how this average idea works:

If only one member goes to the trip, it will cost him/her $1000+$200 = $1200.

If two members go to the trip, then they will share the cost as per the following: ($1000+ $200 + $200 = $1400) which they will be dividing into two people, thus costing each of them $700.

Notice that the general function that represents such average will be given by: f(x) = \frac{1000+200x}{x}

Plot such function in the two dimensional plane, and you will get the asymptotic behavior shown in the attached image.

She is correct because a negative subtracted by a negative is positive.

Is this the correct answer?
Westkost [7]

To be honest, these answer choices are a bit baffling. The best answer in my opinion would be to do at least two of the three options given below.

  1. Place a price floor above the equilibrium.
  2. Decrease imports from other countries.
  3. Reduce current supply (reduce herd sizes).

Doing that should increase the prices.

Placing a floor above equilibrium will force the equilibrium to move upward, and with the reduce in supply from other countries, demand will shift toward the domestic producers. Without the demand shift, there simply would be an oversupply or surplus of dairy. Either the surplus is thrown away or its simply housed somewhere else (often at taxpayer expense).

---------------

If you place a ceiling below equilibrium, then the price will go down to that ceiling value. That will be the highest price possible. This is the opposite of what the farmers want. It gets even worse when you increase milk imports (since supply goes up leading to further reduced prices). So that rules out choice A.

If you place a ceiling above equilibrium, then nothing happens. The price stays at equilibrium. Nothing too exciting here. This rules out choice B (though I agree with the "decrease imports" portion).

If you set a floor below equilibrium, then nothing happens similar to the last paragraph above. The price stays where it is. We can rule out choice C. Reducing herd sizes will reduce supply so that could maybe increase prices.

I'm not really familiar with the term "arbitrage" so I probably won't be any help here. That seems like an answer choice that is a distraction, but I'm not sure.
