1. ## Intro to Statistic problem's

A. Examine Figure 14-9, Using Table D and reading values across the top row, select a random sample of 5 states and compute the mean number of electoral votes.

Table D: 10480150110153602011816479164667179141946259036207 20969995709129190700

B. next, select a systematic sample (every 10) of 5 states (#10, #20, #30,..., #50) and compute the mean number of electoral votes.

C. Compute the population mean and compare.

Use table D as a source of random number, take it two digits at a time, and
treat 00 as 50 and if the two digit number NN is >50 use NN-50, This you
have a sequence of random state numbers.

The first five such numbers are: 10, 48, 01, 50, 11. So select these states as your sample.

Now consult your notes and compute the mean number of electoral votes
for this sample.

3. thank you very much CB

Thanks CB

Table 14-9
9 3 7 6 47 8 8 3 21 12 4 4 24 12 8 7 9 10 4 10 13 20 10 7 11 4 5 4 4 16 5 36 13 3 23 8 7 25 4 8 3 11 29 5 3 12 10 6 11 3

Table D
10 48 01 50 11 01 03 10 20 11 31 14 29 16 46 17 17 41 41 44 12 09 03 12 07 20 46 49 45 20 41 29 19 07 50

A. Do I pick random 5 out of Table D ex: 11, 11, 46, 44, 07, 20, 50 ?
then the mean should be = 27 ?

CB please explaine more for me, my english not enough to understand what it was asking.

thank you,
