The honor problem, we have that they conducted a survey in 2018, and they found 200 tacoma residents that they were dealing with, and they sampled from these residents.
00:15
However, these residents, we have 50 are from a small downtown area, and they're small downtown owners, and we have, 50 that are downtown office workers and then we have a hundred who are downtown shopping.
00:51
So everybody has a relationship with being downtown.
00:56
So it asks us what is the major source of bias that everyone has something to do with downtown? and all residents of tacoma would not be downtown people.
01:08
So this is not a simple random sample.
01:13
And that's something we should have.
01:15
Now your next question says something about find the parameter, if unknown, state so.
01:23
Well, the parameter, it says that they want to conduct a survey to determine whether the residents support.
01:30
So you want the proportion who support this downtown revitalization.
01:41
Project.
01:43
So they have to be tacoma residents who support this downtown restoration project...
