Amanda is writing an article for the school newspaper about social media use among teens. She wants to include information about the percentage of the students at her high school using Facebook, Instagram, Snapchat, or Twitter. Instead of doing a census of the 2600 students at her high school, Amanda decides to select a simple random sample of 60 students and ask them to complete a short survey. Which of the following sampling techniques describes a method of selecting a simple random sample that would allow Amanda to estimate the percentage of students at her high school that use each type of social media? Mark one option in each row of the table. Is this a simple random sample? Yes No Amanda asks the 36 student staff members of the school newspaper and A the 24 student staff members of the yearbook to complete the survey. With the assistance of the newspaper's faculty sponsor, Amanda gets a list of every student in her school. She assigns each student a number from 0001 to 2600. Using a random digits table, Amanda selects 60 four-digit numbers, skipping repeats, 0000, and any number from 2601 to 9999. The students identified by these 60 numbers are her sample. Amanda creates an online survey and gets permission to email the link to C every student's school email address. She takes the first 60 students who complete the online survey as her sample. Since the majority of students in the school take math, science and language arts, Amanda asks 20 students in each of her math, science and language arts classes. These 60 students form her sample. Before school on Monday through Friday, Amanda stands at the front door of the school and selects 12 students and asks them to complete the survey. Each student at the high school has a student ID number between 66010 and 662610. Using a random number generator on her calculator, Amanda generates 60 unique random ID numbers between 66010 and F 662610 inclusive. With the assistance of the principal, Amanda gets the names and schedules for the 60 students, contacts them, and they become the sample.
