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:

99% 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 99% confidence interval for the proportion of readers who would like more coverage of local news is (0.3685, 0.4315).

Answer:
radius = 7.0
Step-by-step explanation:
length of arc* 360/ 285 = circumference
-> 34.8 *360/285 = 43.957 cm
circumference = 2*pi*radius
-> 43.957 = 2* 3.14 * radius
->radius = 6.99996 = 7.0 cm
