Answer: simple random sampling
Step-by-step explanation:
- A simple random sampling is a sampling method in which individuals are chosen randomly from the population. In this each individual has equal chances to get selected.
- If N is the population size , then for any individual , the chances for getting selected is .
As per given , the company randomly selects 50 customers directly from the database without applying any further steps and asks them about their level of satisfaction with the company.
Thus , the sampling technique used here is simple random sampling.
You need to ensure the denominators are the same. To do this you multiply the denominators together.
1/90 + 2/90
However, this is incorrect, as you need to do the same to the numerators, so for the left hand side you multiplied by 9 and for the right hand side you multiplied by 10, so you must do the same for the numerators.
So it should be:
9/90 + 20/90
You can now add this together, to get:
29/90
This is triple checked so I’m not sure why it says reduce the answer fully as that is as far as it can be reduced.
