A review of the Global equity markets, including Europe, Asia, the U.S. and the Americas. Discuss the changes and what the financial press is claiming the causes are. Also include one stock that had a large price change and what caused what it.

Here is an example:

Stocks:                                    Value:                                     %Change

DOW JONES (US)                24,360.14                                -0.50%

S&P 500 (US)                        2,656.30                                  -0.29%

FTSE 100 (UK)                     7,264.56                                  +1.4%

NIKKEI 225 (JPN)                21,778.74                                +0.55%

HANG SENG (HK)               30,808.38                                -0.07%

S&P/TSX (CA)                      15,273.97                                +0 .03%

RTS (RUS)                            1,104.51                                  -1.83%

review:

• US stocks were down Friday because of political uncertainty, but they were up for the week totals. This is because fears of a trade war are going down and that Trump made it sound like he was open to rejoining the Trans-Pacific Partnership free trade deal.

• The Nikkei went up because fears of military intervention in Syria are lessening.

• The Hang Seng went down because China reported a surprise trade deficit.

1. Batesian mimicry occurs when a non-toxic or harmless organism looks highly similar to an organism that is toxic or venomous. An example is the viceroy butterfly which is harmless, but looks extremely similar to the monarch butterfly, which is toxic and bad-tasting when eaten. As a result of the similarity, the harmless organism may be avoided by predators. Bright colors are often advertisements for toxicity, to alert predators to avoid the animal.

   Another familiar example are coral and king snakes. Coral snakes have highly toxic venom, but king snakes are harmless. A common means for distinguishing the two is, "red touches yellow, you're a dead fellow. Red touches black, you're okay, Jack." But is the similarity as useful in the extreme reaches of the snakes' range? If king snakes live in areas where predators have little or no exposure to coral snakes, they are actually in danger, as their bright colors make them more apparent to predators. Researchers investigated the predation rates on king snakes at varying distances from the boundary of coral snakes' range, to determine whether there was an effect.
   
   Here is a link to a Google Sheet of the dataset.

   "Dist. From Boundary" is the distance in kilometers from the edge of the coral snakes' range; negative numbers mean within the range, positive numbers are outside.

   "Proportion of Attacks on Mimics" is the proportion of attacks on artificial mimic snakes vs. artificial non-mimics by predators.
   
   Use the data set to perform a linear regression relating distance from the boundary to the proportion of attacks on mimics. Use your regression formula to predict the proportion of attacks on mimics at 62 kilometers from the boundary. Report your answer to two decimal places.

QUESTION 19

1. Using the same data set from the coral and king snake question on linear regression, perform a t test to demonstrate the slope of the line is not equal to zero. Use the regression feature in the Analysis ToolPak add-in for Microsoft Excel to perform the calculation. Report your p value rounded to four decimal places.

QUESTION 20

1. Based on the p value for the t test on the slope of the line concerning king snakes and coral snakes, which of the following are false statements?

   		The null hypothesis, stating that the slope of the line is equal to zero should be rejected.
   		The null hypothesis stating that the slope of the line is equal to zero should fail to be rejected.
   		The calculated t statistic is less than the critical value of t.
   		The calculated t statistic is greater than the critical value of t.

Transmembrane proteins are often found at the boundary of lipid rafts. Considering the physical properties of the proteins and lipids, involved, what is the best explanation for this arrangement?

Transmembrane domains are usually either a-helical or b-barrel, but not random coil. Why would the random coil conformation be unstable even if all the residues in the segment are hydrophobic?

For the following descriptions, identify a metamorphic rock that would go with them:

a. A magma chamber that intruded where a swamp used to be.

b. A deposit of clay/mud at a convergent plate boundary.

c. A magma chamber that intruded at an old beach (be sure to include a color).

d. A high grade rock found in a mountain range

S(x) is a cubic spline for the function f(x) = sin(pi x/2) + cos(pi x/2) at the nodes x_{0 ⁼} 0 , x₁ = 1 , x₂ = 2

and satisfies the clamped boundary conditions. Determine the coefficient of x³ in S(x) on [0,1] ans. pi/2 -3/2

12. There are many public policy reasons for the adverse possession doctrine. Select three.

a. Resolving boundary disputes

b. Resolving title concerns

c. Assuring property is put to productive use

d. Avoiding unnecessary paperwork

e. Moving to electronic record keeping

f. Assisting the poor in obtaining property
