Question

Analytic Chemistry

1. Use the given choices below to describe the set of data collected. Data is determined to be accurate if the % error is ≤ 5.00% and precise if the SD ≤ 0.10.

Length measurements of a 1.00 ft ruler were recorded as follows: 12.0 inches, 11.9 inches, 12,1 inches

A. precise only

B. accurate only

C. neither accurate nor precise

d. both accurate and precise.

2.Use the given choices below to describe the set of data collected. Data is determined to be accurate if the % error is ≤ 5.00% and precise if the SD ≤ 0.10.

Mass measurements of a 10.00 g standard collects the following masses after three trials: 10.99, 10.98, 10.99

A. precise only

B. accurate only

C. neither accurate nor precise

d. both accurate and precise.

Answer 1

1) Pricise only

2) Both accurate and precise.

a)Production possibility frontier shows the cost incurred in producing one product against another. At efficiency a movement along the curve measures how many of one product must be sacrificed to make another. This is why the the curve is bowed outward because as a country makes more of a product it becomes more difficult to increase production.

b.) Any point inside the shaded region that is not in the outer parts of the curve is possible but inefficient. Any point that is not inside the shaded region requires more resources than area available and are thus not possible to achieve.

c. Doves would prefer a point that produces many butter than guns because they like peace. On the other hand the Hawks would choose a situation where many guns are being produced because they like security.

d.) The decrease in demand for guns would provided a larger “peace dividend” to the hawks because of the steepness of the production frontier. For each gun that the hawks would stop producing they would be able to make a more amount of butter than the doves would be able to while forfeiting the same amount of guns.
