You want to conduct a survey to find out what sport the students at your school prefer to play.

a) you interview 20 boys playing football at lunch. is this a random sample ? explain

b)the survey question you ask is, "what is your favorite sport to play? " is the question fair or biased? explain

plz

a) When interviewing 20 boys playing football at lunch, it is considered a random sample because you are interviewing with a large group of boys.

b) Even though I think is biased, I also think its fair, because of the fact that you are not really sure that their favorite sport is football. It doesn't say like "Oh, they must love playing football and think that's their favorite sport". So it is fair to ask this question, because maybe, that is not their favorite sport.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
