In a survey of 2257 adults, 716 say they believe in UFOs. Construct a 99% confidence interval for the population proportion of adults who believe in UFOs.
A 99% confidence interval for the population proportion is (0.292.0.3427)
(Round to three decimal places as needed.)
Interpret your results. Choose the correct answer below.
O A. With 99% confidence, it can be said that the sample proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.
OB. The endpoints of the given confidence interval shows that 99% of adults believe in UFOs.
C. With 99% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.
XD. With 99% probability, the population proportion of adults who do not believe in UFOs is between the endpoints of the given confidence interval.

C. With 99% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.

Step-by-step explanation:

A confidence interval let us make an inference about a population parameter from a sample statistic. In this case, a sample proportion let us infere aout the population proportion with a certain degree of confidence.

With this confidence interval, we are 99% confident that the polpulation proportion falls within this interval. This means that there is 99% chances of having the population proportion within this interval.

To estimate the population proportion of adults who do not believe in UFO's we should have to construct another confidence interval with the proportion (1-p), but this parameter can not be estimated from the confidence interval for p.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
