Describe a process used to draw simple random sample of size 10 from a group of 87 people.

The entire group or set of items or individuals from which the sample is drawn.

For the following, identify which type of sampling technique was used.To obtain a sample of the employees at a social media marketing company, 100 employees are randomly selected from a numbered list of the 1000 employees.

(a)A manager at a bus company wants to survey employees about the new uniforms. Which of the following best describes a random sample of employees?The manager asks for volunteers and selects every volunteer until 60 employees are selected. She selects the volunteers because these employees are easily accessible.The manager forms groups of 12 employees based on the departments the employees are in. Then, she selects all of the employees in 5 randomly chosen groups.The manager uses a computer program to draw 60 employees at random and selects these employees.

Which of the following best describes a stratified sample of workers?The consultant forms groups of 8 workers based on the lengths of time the workers have worked at the factory. Then, he randomly chooses 9 groups and selects all of the workers in these groups.The consultant assigns each worker a different number. Using a random number table, he draws 72 of those numbers at random. Then, the consultant selects the workers assigned to the drawn numbers. Every set of 72 workers is equally likely to be drawn using the random number table.The consultant forms 6 groups of workers based on the workers' shifts. Then, he selects 12 workers at random from each group.(c)A city manager wants to poll residents about a park renovation. Which of the following best describes a convenience sample of residents?The city manager takes a list of the residents and selects every 5th resident until 90 residents are selected.The first 90 residents who walk into city hall one day are easily accessible.

(a)The organizers of a conference want to survey attendees about the registration fee. Which of the following best describes a systematic sample of attendees?The organizers assign each attendee a different number. Using a random number table, the organizers draw 50 of those numbers at random. Then, the organizers select the attendees assigned to the drawn numbers. Every set of 50 attendees is equally likely to be drawn using the random number table.The organizers form 2 groups of attendees based on the attendees' employment statuses. Then, the organizers select 25 attendees at random from each group.The organizers take a list of the attendees and select every 5th attendee until 50 attendees are selected.(b)A chemist at a pharmaceutical company wants to test the quality of a new batch of microscopes. Which of the following best describes a convenience sample of microscopes?The chemist takes a list of the microscopes and selects every 3rd microscope until 72 microscopes are selected.The microscopes in the first shipment that was received are easily accessible. So, he selects all 72 of the microscopes in this shipment.The chemist assigns each microscope a different number. Using a random number table, he draws 72 of those numbers at random. Then, he selects the microscopes assigned to the drawn numbers. Every set of 72 microscopes is equally likely to be drawn using the random number table.(c)Counselors at a college want to poll students about how much time the students spend studying. Which of the following best describes a stratified sample of students?The counselors form 4 groups of students based on the numbers of classes the students are taking. Then, the counselors select 16 students at random from each group.The counselors form groups of 8 students based on the students' majors. Then, the counselors select all of the students in 8 randomly chosen groups.The students living in a particular dorm building on campus are easily accessible. So, the counselors select the 64 students living in that particular dorm building.
