To solve the problem using the provided table of random numbers, we first need to clarify the task.

Based on your description, the goal is to develop a profile for the 2,500 managers at Electronics Associates, Inc. To do this, you need to select a sample using random numbers, based on the first row of the table you provided (Table 7.1). This row contains a series of random numbers that we will use to help select a random sample from the total population of 2,500 managers.

The specific details of how to use these random numbers depend on how you want to structure the sample. Typically, we follow these steps:

1. Assign numbers to each manager: If there are 2,500 managers, you would assign each one a unique number from 1 to 2,500.
2. Determine the sample size: This was not explicitly mentioned, but you would generally want a representative sample (e.g., 10 managers, 100 managers, etc.).
3. Use random numbers: Select random numbers from the first row of the table that correspond to the manager numbers. If the random number exceeds 2,500, you would disregard it and select the next one. We also must handle cases where there are duplicate numbers.

I can proceed with showing how to select the first 10 managers using the table's first row of random numbers.

Would you like me to continue with this procedure and sample size of 10, or do you have a different sample size in mind?
