10. Labor endowment in country A and B are 1000 and 2000 respectively. The labor productivity for good x in country A is 5 units of labor per unit output and for good Y in country A is 10 units of labor per unit output. The labor productivity for good x in country B is 10 units of labor per unit output and for good Y in country B is 4 units of labor per unit output.

Draw and answer the following:

Price Ratios before trade

Pattern of trade

World Pre trade production

World Post trade production

Gains from trade and trade triangle

If international price ratio were closer to country A’s pre trade price ratio which country benefits the most from trade and why?

Does it matter where the consumer is consuming pre trade in this model? In other words, does it impact pre trade prices?

In 2000, women held 45% of jobs classified as executive, administrative, and managerial. But, in 2011, women held only 16.1% of Fortune 500 board seats, filled only 14.1% of corporate officer positions, and were 7.5% of the country’s top earners. Citing gender stratification in the workplace, in your own opinion why do you think women are being held back from obtaining these top positions?

In​ 2010, a survey of 2000 homes in a region found that 500 had overestimated market values. Suppose you want to estimate​ p, the true proportion of homes in this region with market values that are overestimated.

The point estimate is 0.25

1) Find a 90​% confidence interval for p.

2) Give a practical interpretation of the confidence​ interval

3) Suppose a researcher claims that p equals= 0.18. Is the claim​ believable? Explain.

Starting on September 1, 2000 - the day he starts college - and ending on September 1, 2004, Craig borrowed $6500 a year to pay for college expenses (i.e. that's 5 withdrawals total).
After graduation, he decided to go to graduate school in mathematics, and his loans were deferred (i.e. they accrued interest, but no payments were due). After finishing graduate school, he began repaying his loans. Beginning on July 1, 2007, he made monthly payments for 8 years. Each payment increased by 2.6% over the previous payment. If his loans had a fixed nominal rate of 6% convertible monthly for the entire life of the loans, what was the size of his first payment?

According to a national statistics bureau, in 2000, 21.8% of males living in the Southwest were retired exterminators. A researcher believes that the percentage has increased since then. She randomly selects 275 males in the Southwest and finds that 68 of them are retired exterminators. Test this researcher's claim at the 2% level of significance.(Round to two decimal places)

(a) Critical Value:

(b) Test Score

(c) Construct a 98% confidence interval for the proportion of retired exterminators. (Round to 2 decimal places)

Consider a medium where the speed of sound is 354 m/s. In this medium, a 2000 Hz sound wave is incident on two slits 30.0 cm apart. This creates an interference pattern on a distant screen. In analogy to double slit interference of light waves, the equation d sin ✓ = m can be used to find the location of the maxima, in the same way that it does for Young's double slit experiment with light.

(a) At what angle is the first maximum located? State your answer in degrees.

(b) If the slit separation is 1.00 µm instead and light waves are used instead of sound waves, what frequency of light gives the same first maximum angle as in (a)?

(c) How many maxima are there on the screen in case (a) (counting the maximum at the centre and the maxima on both sides of the center)? How many maxima are there in case (b)?

Starting on September 1, 2000 - the day he starts college - and ending on September 1, 2004, Craig borrowed $4000 a year to pay for college expenses (i.e. that's 5 withdrawals total).
After graduation, he decided to go to graduate school in mathematics, and his loans were deferred (i.e. they accrued interest, but no payments were due). After finishing graduate school, he began repaying his loans. Beginning on July 1, 2007, he made monthly payments for 11 years. Each payment increased by 1.5% over the previous payment. If his loans had a fixed nominal rate of 6.6% convertible monthly for the entire life of the loans, what was the size of his first payment?

If Bob buys a backhoe for $100,000, which has a maintenance cost of $2000/yr that will increase $1,000 per year after year 5, has a required rebuild of its hydraulic system at year 6 that costs $12,000, and then he sells it for $20,000 after 10 years, what is the life cycle cost of his backhoe if the interest rate is 3% per year. PLEASE INCLUDE A CASH FLOW DIAGRAM or I will not rate!! Thank you.
