Design and Analysis by Sharon Lohr, 2nd editon... Textbook Question 28
In an SRSWR, a population unit can appear in the sample
anywhere between 0 and n times. Let
Qi
and
N
ˆt = Q y .
a Argue that the joint distribution of Q1, Q2, ... , QN is multinomial with n trials and
p1 = p2 = · · · = pN = 1/N .
b Using (a) and properties of the multinomial distribution, show that E[ˆt] = t.
c Using (a) and properties of the multinomial distribution, find V [ˆt].

I
had a question about Step 5-9. I already completed the general
journal with the entries into the general ledger. Now I need help
creating the adjusted trial balance, I cant get it to equal to
$20,743. Also, I need help completing the financial statements:
income statements, statement of owners equity, and a balance sheet.
*Net Income has to equal $1024 and total assets has to equal
$18,354.
The
question is how can I balance out my adjusted trial balance...
