1. a) The null: The proportion of registered voters who are planning to vote for the incument president <0.5
The alternative: The proportion of registered voters who are planning to vote for the incument president ≥0.5
b) Test statistic=(636/1200-0.5)/sqrt(0.5*0.5/1200)=2.08
c) CV is Z0.05=1.64
d) From the standard normal table, the p-value for the test statistic, z = 2.08 is 1-0.9812=0.0188.
e) Since p-value is lower than 0.05, we reject the null and conclude that the proportion of registered voters who are planning to vote for the incument president increases significantly at 5% significance level.
f) We say the proportion of registered voters who are planning to vote for the incument president increases significantly, while in fact it does not.
g) We say the proportion of registered voters who are planning to vote for the incument president does not increases significantly, while in fact it does.

Q7 (10 points)
(Part A is worth 5 points; Part B is worth 5 points)
Leave numbers in generic form such as: $e^$, $\ln( )$, $\sqrt{*}$, etc., if applicable. No decimal numbers.
Part A. If $\displaystyle f(t) = 5\sqrt{t} – \frac{1}{t}$ for $t>0$ and $g(x,y) = x^2+y^2-5$, determine where $(f \circ g) (x,y)$ is continuous.
Part B. Given that $z=y^3 \sin(4x) + (x+x^2)^{\cos(x)}e^{-x^4} + \cos(3x) \arctan(y^2+1) \ln(y^3+42)$, find $\displaystyle \frac{\partial^2 f}{\partial x \partial y}$ when $x=\pi$ and $y=0$.

Question 1)
(a) Show that, by choosing suitable values for P and Q, Green’s Theorem in the
plane leads to the formula for the area enclosed by a loop i.e.,
Area =
1
2 ˛loop

(b) Use this to find the area of the closed curve defined by
x = cos 
y = 3 sin 

Question 2)
Consider the vector field, F = x2yz i+xy2z j+xyz2 k. Use the divergence theorem
to evaluate

Question 3)
Consider the vector field F = (2x+yz) i+(2y+xz) j+xyk. Using Stokes’ theorem,
show that ¸ F · dr = 0 around any closed curve. [2 marks]
Question 4)
Consider the vector field, F = y i+x k. Use Stokes’ theorem to find ¸ F·dr around
the circular loop in the xy-plane defined by x2 + y2 = a2. [4 marks]
Question 5)
For gravity, g, we can define the divergence as, ∇ · g = −4G, where G is the
gravitational constant and  is the mass density. The divergence theorem states that,
“S
g · ds = °V
∇ · g dV.
By applying the divergence theorem to a point within the Earth’s radius, a distance

(a) Draw a sketch showing a suitable choice of surface, S. [2 marks]
(b) Show that the magnitude of g is given by:
g(r) = −

(Assume that the Earth has a constant density.) [2 marks]
Question 6)
The square OABC lies in the xy-plane and is defined by the points:
O = (0, 0, 0);A = (1, 0, 0);B = (1, 1, 0);C = (0, 1, 0). The vector field, b, is given by,
b = 2yz i + (x2 − y2) j + (y + x2 − z2) k.
(a) Evaluate the line integral, I1 = ¸ b · dr, following the path O-A-B-C-O.
