In this exercise, we are told that two poles have taken place.
00:06
And in one of the polls, we are asked this question.
00:09
And in the second poll, we are asked this question.
00:13
And the only difference is the order of the words, fairly or unfairly.
00:23
And so in the polls, we had both of them were size 510.
00:35
And the sample proportions were as follows.
00:38
So when worded this way, in the first poll, 58 % of people said, the death penalty was administered fairly.
00:50
And in the poll where the question was worded this way, only 54 % said that the death penalty was administered fairly.
01:00
And so for part a, we are asked what kind of bias may be presented here.
01:04
And the issue may have to do with word bias.
01:06
So often when you pose a question a certain way, and you're comparing between two possibilities, often the one presented first is the one that sort of leads the person who's listening to the question.
01:20
So if you are given the first question, you might be kind of led to believe that there's something unfair going on.
01:27
There's something fair about this situation.
01:30
Whereas if the question is led with the word unfairly, you might be led to believe that there's something unfair going on with the application of the death penalty.
01:40
So we may have an issue of wording bias.
01:51
So in part b, we were told that if we consider combining the two groups into one larger group.
01:56
So then we would have a sample size of 120.
02:01
And since poe number one and poe number two were exactly the same sample sizes...
