Answer:

Variance = 0.02141851

Explanation:

We first calculate the mean for the stocks

Mean = (0.1858 - 0.0558 + 0.2081) / 3

Mean = 0.3381 / 3

Mean = 0.1127

Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1

Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2

Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2

Variance = 0.04283702 / 2

Variance = 0.02141851

The variance of returns is 0.02141851

goblinko [34]

Answer:

Predicted exchange rate = Country price of Big Mac/ US price of Big Mac

Predicted exchange rate:

Chile = 2,050 / 4.37

= 469.11 Pesos / US dollar

Hungary = 830 / 4.37

= 189.93 Forints / USD

Czech Republic = 70 / 4.37

= 16.01 Korunas / USD

Brazil = 11.25 / 4.37

= 2.57 Real/ USD

Canada = 5.41 / 4.37

= 1.24C$/ US$

According to purchasing power parity, the predicted exchange rate between the Hungarian forint and the Canadian dollar is 153.42 Forint per C$. However, the actual exchange rate is 217 Forint per Canadian Dollar.

Predicted exchange rate = 830 / 5.41 = 153.42 Forint per C$

Actual Exchange rate = 217/1 = 217 Forint per C$

Answer:

$10,000 loss

Explanation:

Barry bought a property for $60,000. He sells it for $100,000 to a company he owns 50% of. 50% of $100,000 = $50,000. He bought it for $60,000 and sold it for $50,000... that's a $10,000 loss. But they did say they are keeping the property for resale so there still may be hope :D
