def factors(matrix, factor):
The matrix is a 3D list of integers.
factors are either one, two, or three
If the factor is 'one' it will return a the first value from each list
if the factor is 'two' it will return the second value, and same for the third.
Example;
input = [ [ [1, 2, 3], [3, 2, 9], [9, 8, 6] ],
[ [0, 0, 4], [8, 9, 0], [5, 2, 1] ],
[ [0, 1, 1], [5, 5, 9], [3, 8, 4] ] ], 'one')
output = [ [1, 3, 9], [0, 8, 5], [0, 5, 3] ]

Q3. Hypothesis: Informing people about recycling causes them to recycle more.
Study design: 50 households were randomly assigned to a treatment group where they were
informed by letter about proper recycling habits and its benefit on environment, while 50
different households were randomly assigned to a control group that did not receive such a letter.
After 3 months, the weekly average recycling amount in the treatment group was 12.4 lbs (
sd
=
2.5), while the weekly average recycling amount in the control group was 3.7 lbs (
sd
= 1.1)

Lottery – Let $1,000 be your current wealth. There are 100 people and each buys a lottery ticket at $5. The administrative cost of the lottery ticket per person is $5. If you win the lottery, you will get $500. There is only one person who can win the lottery. (The cost is 5+5 not 5)
a. Define the gamble
b. Calculate the expected value of the gamble
c. Is this gamble favorable, fair, or unfavorable?
d. Now, suppose your utility function is ? = ?5/2 . Calculate the Certainty Equivalent and the risk premium for individual willing to buy the lottery (i.e., minimum amount of money he/she needs to receive to forgo the lottery)?.
e. Now suppose that there are only 50 individuals participating in the lottery. Without calculating all the math again, what happens to risk premium? Does it increase, decrease, or stay the same?

1. For each of the scenarios below construct a decision chart (correct and incorrect decisions) similar to Table 5-3 in the textbook, but be sure to explain what each decision means in terms of your scenario descriptions. In other words, you need to provide me more than simply Type I or Type II error in each cell of the matrix – spell it out in words – at least a sentence or two.
a. A study working with premature infants to determine if they are delayed in recognizing voices.
b. A study to determine if turning on both muscle producing genes in mice increases the strength of the mice.
c. A political study focusing on the effect of credibility on the interpretation of proposed promises.

1. Give, using “big oh” notation, the worst case running times of the following procedures as a function of n ≥ 0.
(a). procedure unknown

2.
The function max (i, n) given below returns the largest element in positions i through i + n – 1 of an integer array A. Assume for convenience that n is a power of 2.
function max(i, n)
if n = 1 then
return (A[i])
else
m1 ← max (i, n/2)
m2 ← max (i + n/2, n/2)
if m1 < m2 then
return (m2)
else
return (m1)
endif

(a). Let T(n) denote the worst-case time taken by max with the second argument n. Note that n is the number of elements of which the largest is to be determined. Write an equation expressing T(n) in terms of T(j) for j < n and constants that represent the times taken by statements of the program.
(b). Obtain a big theta bound on T(n).

Suppose two blocks of iron, each having 1 mol of iron atoms, are at differing temperatures and are then brought together in an otherwise isolated system. One of the blocks is at 273.15 K and the other is at 373.15 K and the process is carried out at 1 bar pressure.
a.) Would you expect ∆Ssys < 0, ∆Ssys = 0, ∆Ssys > 0 ?
b.) Using common sense and high school physics (and perhaps the First Law), what is the common final temperature of the two blocks?
c.) Calculate ∆Ssys for the process (use Table 4.1 for any needed molar heat capacities needed, and assume that the molar heat capacities are independent of T).
d.) What is q for the isolated system? How does this value of q and the result of part C relate to the Clausius inequality: final initial d q S T − ∆ ≥ ∫ ?
e.) Interpret this change in entropy in terms of the ordering-disordering effects involved in the transfer of given amount of heat from a block at higher temperature to one at a lower temperature (i.e. the disordering effect of adding a given q to the cooler block vs the ordering effect of removing the same q from the hotter block).
Molar heat capacity of Fe(s) ==> Cp,m (J / mol*K) = 25.1
