Question

A computer company employs 100 software engineers and 100 hardware engineers. The personnel manager randomly selects 20 of the software engineers and 20 of the hardware engineers and questions them about career opportunities within the company. Does this sampling plan result in a random sample? Simple random sample? Explain.

Answer 1

Yes, it is a Simple Random Sampling.

Explanation:

Since the computer company has two equal groups software engineers and hardware engineers and equal units are randomly selected from each group. So, it is Simple Random Sampling.

Further, Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.
