Okay, what we want to do is we want to walk through the process of being able to use a table d or be, depending on your textbook, the random digit table to do some random selections.
00:14
And so we're told that a club has 30 student members, and they give you the list of the 30 last names.
00:27
And it also has 10 faculty members.
00:32
And once again, it's given a list of faculty members, their last names.
00:38
And the club can actually can send only four students and two faculty members to a convention.
01:02
And how are we going to do a random selection to be able to determine who goes to that convention? okay, so what i propose to do is we are actually going to let the number 0 to 29 be your student members.
01:31
And we're actually going to let 0 be and we're just going to do it in the order in which the last names were told so is able 01 is fisher 0 .2 is i think it was like cube or something like that and we're just going to keep going to list all 29.
02:06
To 99 or skips.
02:11
So if we hit one of those, we're going to skip them.
02:14
Okay.
02:16
And then we're also going to, because it's stratified, we're going to then let for a second round, zero to nine be faculty member.
02:34
And you could do zero is andrews, one is fernandez, two is kim, and et cetera, right? okay.
02:56
And so what we're going to do is for the first round, starting on at line 123, and using two digits okay so if i come back here at 23 doing two digits and we might need to make that bigger i wonder if i can make this bigger so if i do it at 23 my first number is 54 i've got to skip 54 because he is a skip, right? fifty -eight's a skip.
04:00
My first number is, whoops, my first number is a, that i come to is a 08, then a 15, then a 07, then a 27...
