Answer:
p < 5
Step-by-step explanation:
We want to find p for ...
1.5p -1 < 1 +1.1p
0.4p < 2 . . . . add 1-1.1p
p < 5 . . . . . . . multiply by 2.5
The desired relationship will be the case for values of p less than 5.
- 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%).
