can someone help me with this??

I'm pretty sure the word "lengthy" constitutes an opinion.
a) it isnt a random sample because some kids might leave school earlier (or later) , and there is no indication he did a random sampling either
b) it is biased because he asked the question 'is the lengthy school day' , which gives the impression that it is a lengthy day , or it is well known it is lengthy
the question presupposes that it is a lengthy day, but you want the questioner to decide that
As for c, the number who answered no is 54 -51 which is 3 divide 3 by 54 and multiply by 100, to get the percent.
he just surveyed people convenient that he met. this is an observational study of convenience, not a random sample .
so b would be biased because of the word 'lengthy'? so in this case my answer would be 'This is a biased question, because it makes the opinion about the day be long.'
yes
it is not random because there are many people who are left out of the sample, people who stay later , who leave early, who didnt show up (sick, playing hookey)
So is this the right answer's a. This is not a random sample, because some children may get out of school late (or early), and there is no indication he did a random sampling. b. This is a biased question, because it makes the opinion about the day be long. c. Divide 3 by 54 and multiply by 100, to get the percent. 54/3=18 18*100=

c) (54-51)/54 = 3/54
so the percent is 0.055555555555556
or 18?
