You are experiencing pressure from administrators to cut the Peer Mentor Program in order to save money. Their argument is that the Academic Success Program alone is enough to help students succeed. After meeting with students and their peer mentors, you feel confident that the Peer Mentor Program provides something that the Academic Success Program does not: a greater feeling of being connected to the campus community. To support your argument, you have the students complete the Connected On Campus Scale at the end of Year 1. You need to compare Groups 1 and 2 on their Connected On Campus Scale (COC) scores at the end of Year 1, to determine whether your argument is true. Select the appropriate test to perform and conduct a two-tailed testusing an alpha of .05. Use r2 for your effect size.

Because there are infinitely many primes, we can assign each one
a number: p0 = 2, p1 = 3, p2 = 5, and so forth. A finite multiset
of naturals is like an ordinary finite set, except that an element
can be included more than once and we care how many times it
occurs. Two multisets are defined to be equal if they contain the
same number of each natural. So {2, 4, 4, 5}, for example, is equal
to {4, 2, 5, 4} but not to {4, 2, 2, 5}. We define a function f so
that given any finite multiset S of naturals, f(S) is the product
of a prime for each element of S. For example, f({2, 4, 4, 5} is
p2p4p4p5 = 5 × 11 × 11 × 13 = 7865.
(a) Prove that f is a bijection from the set of all finite
multisets of naturals to the set of positive naturals.
(b) The union of two multisets is taken by including all the
elements of each, retaining du-plicates. For example, if S = {1, 2,
2, 5} and T = {0, 1, 1, 4}, S∪T = {0, 1, 1, 1, 2, 2, 4, 5}. How is
f(S ∪ T) related to f(S) and f(T)?
(c) S is defined to be a submultiset of T if there is some multiset
U such that S ∪U = T. If S ⊂ T, what can we say about f(S) and
f(T)?
(d) The intersection of two multisets consists of the elements that
occur in both, with each element occurring the same number of times
as it does in the one where it occurs fewer times. For example, if
S = {0, 1, 1, 2} and T = {0, 0, 1, 3}, S ∩ T = {0, 1}. How is f(S ∩
T) related to f(S) and f(T

1) Given f(x) = x^2 + x + 1 and g(x) = x^3 + x, compute f(x) * g(x) in GF(2^4) with the irreducible polynomial m(x) = x^4 + x + 1.
1.5) Give the set of polynomials for finite field of the form GF(2 4 ).

The purpose of this exercise is to show how the public sector will allocate private and public goods. Unlike the private sector the public sector decision to provide a good is based on a collective political decision rather than a market based decision. For each type of good your decision to provide the good must meet the following conditions: the total must receive a majority of voting support and it must raise enough taxes to cover costs. Every resident pays the same amount of taxes.
Private Good. In the table below are three individual demand schedules for ECONOBREAD. The weekly amount of bread loaves demanded per week is provided for each price. It costs you $3 to produce each loaf of bread. There are no fixed costs.
Price ($/loaf of bread per week)

Public Good.This good being distributed is a pure public good. Once produced it can be offered to anyone without a reduction in quantity. A firm offers free videos to customers. The table below lists three customers and the value they place on the number of movies offered each week. It costs the firm $8 per video to supply.

1. Write a Racket function (set-equal? L1 L2) that tests whether L1 and L2 are equal. Two sets are equal if they contain exactly the same members, ignoring ordering (or in other words, two sets are equal if they are a subset of each other).
For example (set-equal? '(1 (2 3)) '((3 2) 1)) ---> #t
(set-equal? '(1 2 3) '((3 2)1)) ---> #f
(set-equal? '(1 2 3) '((1 2 3))) ---> #f
2. Two common operations on sets are union and intersection. The union of two sets is the set of all elements that appear in either set (with no repetitions). The intersection of two sets is the set of elements that appear in both sets. Write Racket functions (union S1 S2)and(intersect S1 S2) that implement set union and set intersection.
For example (union '(1 (2) 3) '(3 2 1)) ---> (1 2 3 (2))
(union '((1 2 3)) '((3 4 5))) ---> ((1 2 3) (3 4 5))
(union '((1 2 3)) '((3 2 1))) ---> ((1 2 3))
(intersect '((1 2 3)) '((3 2 1))) ---> ((1 2 3))
(intersect '((1 2 3)) '((4 5 6))) ---> ()
(intersect '((1) (2) (3)) '((2) (3) (4))) ---> ((2) (3))
The ordering of the elements in your answer may differ from the above. You must use recursion, and not iteration. You may not use side-effects (e.g. set!).

groups are
shown in the back-to-back stem-and-leaf plot.
