Help...
The track-and-field coach wants to know whether the students in the entire school prefer track races or field events. The coach draws a random sample from the following groups:
- All students in each grade
- All teachers in the school
- All boys in each grade in the school
- All students on the track-and-field team
Which group best represents the population she should take a random sample from to get the best results for her survey?
To answer your question I have no idea. My thoughts and prayers are with Yemen and I am hoping people will sign petitions and donate. If you can not do that please post about it in your socials or even talk and educate other people on the matters.
