Answer:
c. 0.0819
Explanation:
The mean = 0.85
standard error of the proportion is: sp = sqrt(pq/n)
= sqrt ((.85)(0.15) / 51) = 0.05
P(0.9115 < X < 0.946) = P( (0.9115 - 0.85) / 0.05 < z < (0.946 - 0.85) / 0.05 )
= P(1.23 < z < 1.92)
= P(z < 1.92) - P(z < 1.23) = 0.0819
Answer:
The expected profit is -$13,162.
I would not recomend the investor to make this investment.
Explanation:
The expected profit can be calculated multypling the probabilities of every outcome and the profit of each outcome, and substracting the total invevstment.
The outcomes are:
1) probability 0.39 of a $23,000 loss,
2) probability 0.24 of a $8700 profit,
3) probability 0.12 of a $31,000 profit, and
4) probability 0.25 of breaking even
NOTE: It is assumed that the outcomes does not include the initial investment.
Then, the expected profit of this investment is:
![E(P)=[0.39*(-23,000)+0.24*8,700+0.12*31,000+0.25*0]-10,000\\\\E(P)=[-8,970+2,088+3,720+0]-10,000\\\\E(P)=-3,162-10,000\\\\E(P)=-13,162](https://tex.z-dn.net/?f=E%28P%29%3D%5B0.39%2A%28-23%2C000%29%2B0.24%2A8%2C700%2B0.12%2A31%2C000%2B0.25%2A0%5D-10%2C000%5C%5C%5C%5CE%28P%29%3D%5B-8%2C970%2B2%2C088%2B3%2C720%2B0%5D-10%2C000%5C%5C%5C%5CE%28P%29%3D-3%2C162-10%2C000%5C%5C%5C%5CE%28P%29%3D-13%2C162)
Answer:
84) The equilibrium is the only price where quantity demanded is equal to quantity supplied. At a price above equilibrium, like 1.8 dollars, quantity supplied exceeds the quantity demanded, so there is excess supply.
85) The equilibrium price and quantity are where the two curves intersect. The equilibrium point shows the price point where the quantity that the producers are willing to supply equals the quantity that the consumers are willing to purchase. This is the ideal quantity to supply
86) The existence of economic profits attracts entry, economic losses lead to exit, and in long-run equilibrium, firms in a perfectly competitive industry will earn zero economic profit.
87) The industry is in long-run equilibrium when a price is reached at which all firms are in equilibrium (producing at the minimum point of their LAC curve and making just normal profits). Under these conditions there is no further entry or exit of firms in the industry, given the technology and factor prices.
Explanation:
i dont know 82 or 83 sorry
I believe the correct answer is false. <span>An attractive business climate is not defined by only one dimension: it minimizes the political risk to a company. Other than this, there are other indicators present. Hope this answers the question. Have a nice day.</span>
