Problem 5 Easy Difficulty

In this section we used a two-step procedure to select a simple random sample of 30 EAI
managers. Use this procedure to select a simple random sample of 50 EAI managers.

Answer

There are 2500 managers given in the data list.
Select 2500 random numbers between 0 and 1, each number will correspond with one of the managers.
The sample will then consist of the 50 managers with the 50 smallest random numbers:

Yeah. So here in this section, we used a two step procedure to select a simple random sample of 30 Ai managers were going to use this procedure to select a simple random sample of 50 Eai managers. And so we see that there's 2500 managers given in the data list. Yeah. And the first step that we want to do is to select 2500 random numbers between zero and one. Mhm. Yeah. Yeah, mm hmm. Mhm. And we know that each one of these numbers is going to correspond with one of the managers. Yeah. Mhm. Mhm. Mhm. Mhm. And then for step two to choose our sample, the sample is then going to consist of the 50 managers with the 50 smallest random numbers. And that's because when we assigned the 2500 numbers between zero and one to each manager that was done randomly. And then we'll just choose the smallest random numbers. Mhm. Mhm. And those managers are a sample.
