Question
![According to a study conducted by a statistical organization, the proportion of people who are satisfied with the way things are going in their lives is 0.78. Suppose that
a random sample of 100 people is obtained. Complete parts (a) through (e) below.
different people feel differently regarding their satisfaction.
D.
The sample proportion p is a random variable because the value of p represents a random person included in the sample. The variability is due to the fact that
people may not be responding to the question truthfully.
(c) Describe the sampling distribution of p, the proportion of people who are satisfied with the way things are going in their life. Be sure to verify the model
requirements.
Since the sample size is no more than 5% of the population size and np(1 - p) = 17.16 2 10, the distribution of p is approximately normal with Ha = 0.780 and
On = 0.041 .
