Answer:
The 95% confidence interval estimate for the true proportion of adults residents of this city who have cell phones is (0.81, 0.874).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval estimate for the true proportion of adults residents of this city who have cell phones is (0.81, 0.874).

It is the graph where the two lines intersect, when they intersect there is a point where they connect, and that is your answer
Answer:
4^2+2^2, 5^2, 6^2-6
Step-by-step explanation:
4 to the power of 2 is 16 and 2 to the power of 2 is 4. 16+4 is 20.
5 to the power of 2 is 25 which is greater than 20.
6 to the power of 2 is 36 minus 6 is 30 which is greater than 25 and 20.
