Describe how to select a stratified random sample of 36 people hired by ETS to score the AP Statistics Exams. Explain your choice of strata.

The strata will be the category of people with at least 3 years of working experience scoring AP Statistics

Step-by-step explanation:

The strata will be the category of people with at least 3 years of working experience scoring AP Statistics Exams.

I will use this strata because it is only those with a track record of scoring AP Statistics Exams that can rightly score for ETS. People who don't have the right amount of experience of scoring AP Statistics exam may need some training because they need to understand the specifics on how to grade some questions and respective answers.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
