You are tasked with assessing the health department’s intervention program in preventing recurrence of acute alcohol poisoning. This is a program made available for free to anyone interested, and all teens arrested or admitted to the emergency department (ED) for alcohol related issues are made aware of the program. You cross-reference ED records from the past 5 years with records of program participation and school performance. You will assess performance in school as well as additional alcohol-related issues.

Lenny is an elementary school principal. He's concerned about how the families at his school are doing currently, so he creates a list of questions to ask some of them to get an idea of how they're holding up.

Match each scenario below with the correct sampling technique.

the previous one I saw it, I wonder how to do the last one.

Read carefully
See the photo of the algorithm below after reading these instructions: write a program in Python 3 which uses a list. Your program will use a list to store the names and exam scores of students. The program starts by asking how many results will be entered. Then a loop will be used to enter the name and score for each student. As each name and score is entered it is appended to a list (which was initially empty). When the loop is finished (i.e. all scores are entered) the program ends by printing the list.

Make a copy of your Lab6A.py file to Lab6B.py. Amend the comments accordingly for these instructions. Send the list you created in Lab 6A to a function which returns a list of names of all above average students.
