Answer:
The distribution of <em>X</em> is Hyper-geometric distribution.
Step-by-step explanation:
A Hyper-geometric distribution is defined as the distribution of the exact number of success in a sample of size <em>n</em> taken from a population of size <em>N</em>.
The properties of a Hyper-geometric distribution are:
- The sample is drawn from a population of finite size, <em>N</em>.
- Each participant, selected in a sample of size <em>n</em>, has only two outcomes, either a success or a failure.
- Each sample is selected without replacement.
In the provided case the random variable <em>X</em> is defined as the number of laser printers sampled.
The population consists of <em>N</em> = 20 printers of which 8 were laser printers and 12 were inkjet printers.
A sample of size, <em>n</em> = 5 is to be selected for inclusion in a customer satisfaction survey.
The success and failure can be defined as:
Success = A printer selected is a laser printer.
Failure= A printer selected is not a laser printer.
The random variable <em>X </em>satisfies all the properties of a Hyper-geometric distribution.
Thus, the distribution of <em>X</em> is Hyper-geometric distribution.
