Directions: Identify which type of sampling is used: random, stratified, cluster,systematic or convenience. Write the answer on the space before each number.__________ 1. An interviewer selects 5 males and 5 females from each of 4 thegroups.__________ 2. A psychologist surveys all students from each of 20 randomly selectedclasses.__________ 3. The organizer writes the name of each participant on a separatesheet. He shuffles the sheets, and draws 10 names.__________ 4. Smart selects 50th cell phone from the assembly line and conduct athorough test of quality.__________ 5. When a principal made an important announcement, he basedconclusion on 1 000 responses from 10 000 questionnairesdistributed to students.

Professor Romano looks at ways to improve student learning. She wants to recruit participants at high schools in town to see how the use of repeated quizzing may boost performance on later exams. Because she works with the local public school system, they are willing to let her have access to any schools she wants. She randomly selects 5 schools, and within each school, she randomly selects 5 classes to participate in her study. What kind of sampling is this?Group of answer choicescluster samplingstratified random samplingsimple random samplingconvenience sampling

(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. Every set of 60 employees is equally likely to be drawn by the computer program.(b)A consultant wants to ask workers at a factory about the workers' job satisfaction. 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. So, the city manager selects these residents.The city manager forms 5 groups of residents based on the residents' incomes. Then, she selects 18 residents at random from each group.

A teacher surveys 64 children on how they travelled to school.20 of the students were in Year 7.The teacher surveyed 30% more students in Year 9 than in Year 7.The rest of the students surveyed were in Year 11.75% of the students in Year 7 walked to school.8 more students in Year 9 walked to school than did not walk.Out of students surveyed, more Year 11 students walked to school than Year 9students.One of these students is picked at randomWrite down the probability that the student chosen will walk to school.......................(4)© CORBETTMATHS 2024
