Assume the following facts:
A political polling organization conducted a survey. As a part of the survey, the organization
calls 1,012 people and asks, “Do you approve, disapprove, or have no opinion of the way the president is handling his job?”
The random variable x represents the number of people who approve of the way the president is
handling his job.
* * * * * *
1. Is the given experiment a
binomial experiment?
2. Assume that the polling question
is revised to: “Do you approve or disapprove
of the way the president is
handling his job?”
The random variable x represents
the number of people who
approve of the way the president
is handling his job.
Now, this question represents a
binomial experiment. Determine
which of the following outcomes
will denote “success” for this
experiment.
• No opinion
• Approve
• Disapprove

1.No because there are more than 2 outcomes
ReplyDelete2.Approve and disapprove will give successful outcomes to the new question since it is now based on 2 outcomes; pass or fail

1.No, cause there are more than two possible answers
2.Turns binomial due to only two possible answers, which are approve and disapprove.

1. No, it is not a binomial experiments because it has more than two possible outcomes.
2. Approve
1. No, this is not a binomial experiment because there are more than two possible outcomes.
ReplyDelete2. It depends on which outcome you identify as a success.
1. No it is not a binomial experiment because there is a 3rd option, “have no opinion”. This 3rd opinion cannot be catalogued as a success or a failure. It is not a yes or no statement.
ReplyDelete2. Yes it is a binomial experiment. “Approve” is a success. P. 184
No this is not a binomial experiment becuase to be defined as such you have to have 2 outcomes yes no, win lose, and this has more than that.
ReplyDeleteApprove is the success
