    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.

    Please help,
    thanks in advance.

    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.

    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,
