Answer: %512 increase.
Step-by-step explanation:
Soooo if you had $1 and the prize was $512, then youd be making $512 (because you lost/invested the $1), It would be a 512% increase. Now, if it was $51,200 youd win, then yes it would be a 51,200%, but its only $512.
- The margin of error of the proportion given is of 2.9%.
- Applying the margin of error, the confidence interval is (29.1%, 34.9%).
-----------------------
The margin of error of a confidence interval of a proportion
in a sample of size n, with a confidence level of
, is:

In which z is the z-score that has a p-value of
.
The confidence interval is:

In this problem:
- Poll of 1012 people, thus
. - 32% keep a dog, thus

95% confidence level
Thus
, z is the z-score that has a p-value of
, so
.
The margin of error is:

As a percent, 2.9%, as 0.029 x 100% = 2.9%.
Now for the confidence interval, which is <u>percentage plus/minus margin of error</u>, thus:


The confidence interval is (29.1%, 34.9%).
