Answer:
B. 1.291%
Explanation:
The computation of the standard deviation is shown below;
= 2000 + 2001 + 2002 + 2003
= 0.5 × 14% + 0.5 × 16% + 0.5 × 15% + 0.5 × 17% + 0.5 × 16% + 0.5 × 18% + 0.5 × 17% + 0.5 × 19%
= 15% + 16% + 17% + 18%
= stdev( 15% + 16% + 17% + 18%)
= 1.291%
Hence, the correct option is b.
Answer:
The correct answer ise. do nothing and leave prices unchanged.
Explanation:
It has been observed that many oligopolistic industries exhibit an appreciable degree of price rigidity or stability. In other words, in many oligopolistic industries prices remain sticky or inflexible, that is, there is no tendency for oligopolists to change the price even if economic conditions undergo a change.
There have been many explanations of this price rigidity in the oligopoly and the most popular explanation is the so-called crooked demand curve hypothesis. The crooked demand curve hypothesis was presented independently by Paul M. Sweezy, an American economist, and by Hall and Hitch, Oxford economists.
It is to explain the price and production under oligopoly with product differentiation, that economists often use the hypothesis of the crooked demand curve. This is because when products under oligopoly differ, it is unlikely that when a company increases its price, all customers abandon it because some customers are intimately linked to it due to product differentiation.
As a result, the demand curve facing a company under differentiated oligopoly is not perfectly elastic. On the other hand, under the oligopoly without product differentiation, when a company increases its price, all its customers leave it, so that the demand curve faced by an oligopolist that produces a homogeneous product can be perfectly elastic.
Before the annual “Blue versus Red” football game, Sara bet on the blue team who later lost. After the game, she claimed she knew the blue team would lose. This illustrates hindsight bias which is also known as knew it all long effector tiptoeing determinism. It is the disposition after an event has occurred, to see the event as having been expectable in spite of there having been little or no objective basis for forecasting it. It is multifaceted phenomenon that can affect can cause exciting methodological problems while trying to analyze, understand and interpret results in investigational studies. In Additional, one example of the hindsight bias is when after viewing the outcome of a potentially unforeseeable event a person believe he or she “knew it all along.”
