Where ranges are given as choices, pick the correct range. For
example, if you calculate a probability to be 0.27, you would pick
0.2-0.3. If your answer is 0.79, your choice would be 0.7-0.8, and
so on. The random variable Z has a standard normal
distribution.
1) Compute the probability that Z<0.6.

A multiple choice exam consists of 25 questions, each with 4
possible answers. Suppose that a student doesn't know the material
and simply guesses on each question.

On November 14, Thorogood Enterprises announced that the public
and acrimonious battle with its current CEO had been resolved.
Under the terms of the deal, the CEO would step down from his
position immediately. In exchange, he was given a generous
severance package. Given the information below, calculate the
cumulative abnormal return (CAR) around this announcement. Assume
the company has an expected return equal to the market return.
(A negative value should be indicated by a minus sign.

Write a function that:
Given a numerical parameter in input, computes and prints all
the prime numbers up to that value.
Example:
If input parameter is 10, output is "2, 3, 5, 7"
If input parameter is 100, output is "2, 3, 5, 7, 11, 13, 17,

Consider a firm that produces a single output with a single
input, labor, using production function F(L)=100L−4(L^2), for
L∈[0,12.5]. The input price is W=2.
1. Determine the firm’s cost function C(Q), that is, the lowest
cost of producing Q units of output. State the associated labor
choice for a given required output, L(Q). Consider only the range Q
∈ [0, 12.5] .
2. What is the firm’s marginal cost curve, MC(Q)?
