what do you think @jim_thompson5910

Answer 6

let's do an example

Answer 7

let's say we wish to find out the proportion of people who would vote for a candidate

if we sample 100 people, then is it guaranteed we will get the same proportion every time?

Answer 8

I don't think you would get the same proportion all the time.

Answer 9

no you wouldn't, it would fluctuate around the true population proportion

Answer 10

so if the true proportion was say 0.48, then some sample proportions would be

0.46
0.45
0.49
0.52
0.47
etc etc

Answer 11

so that would make this false then

Answer 12

yes it is false
