Step-by-step explanation:
To randomly pick the 10 people needed in the sample, it can be done this way
1. Define the population: in this case, the total population is 280 and expressed as N and since we are interested in everyone in the neighborhood with no exclusion, our sampling frame is thus 280 people.
2. Choose your sample size: As given in the question, our sample size is to randomly pick 10 people expressed as n.
3. List your population and then assign numbers to each unit in the population: Getting the list of all 280 people in the population and then assigning numbers from 1 to N - in this case 1 - 280.
4. Then find random numbers using the random number table to help select your 10 people sample making them a representative of the population in residence.
