Question

Let ** lst1 = '(a b c d e)**,

*(append (cons (first lst1) '())*

*(cons (cdddr lst1) '())*

*(cons (proc lst1) '())*

*(cons (proc lst2) '())*

*(cons (fifth lst1) '())*

* )*

a.

*'(a d e c 3 e)*

b.

*'(a d e c 3 d)*

c.

*'(a (d e) c 3 e)*

d.

*'(a (d e) c (3) d)*

e.

*'((a) (d e) (c) (3) (d))*

Answer #1

**The answer is option c. '(a (d e) c 3 e)**

;append function will append all the elements

;(cons (first lst1) '()) will return a (first element in
lst1)

;(cons (proc lst1) '()) will return (d e) (since cdddr will exclude
the first three element and returns the rest of the list)

;(cons (proc lst1) '()) will return c which is the middle element
of lst1

;(cons (proc lst2) '()) will return 3 which is the middle element
of lst2

;(cons (fifth lst1) '()) will return the 5th element in lst1 which
is e

;so the final list of all these elements is (a (d e) c 3 e)

(append (cons (first lst1) '())

(cons (cdddr lst1) '())

(cons (proc lst1) '())

(cons (proc lst2) '())

(cons (fifth lst1) '())

)

Let the population have N=7 units, with {(unit,value)} =
{(A,-1),(B,+1),(C,-2),(D,+3),(E,-4),(F,+5),(G,-6)}. The design is
as follows: first choose A or B at random; if A then choose from
{C,D} at random, if B then choose from {E,F,G} at random. 1) Find
the first-order inclusion probabilities (note that the sample size
n is fixed at 2).
Verify (show numerically for this example) that the
Horvitz-Thompson estimator is unbiased for the population total.
(Hint: find the probability of each sample and the value...

Define variables as follows: a = 1; b= 2; c = 3; d = 4; e = 5; f
= 6; g = 7; h = 8; i = 9; j =10; Using Matlab operations (no
hard-coding), perform the following operations (in order): 1a) Add
one to the value of a, and store the result in a 1b) Cube b, add
the value of c to this, and store the result in b 1c) Set c equal
to the larger...
