Question

According to a recent survey of 1,200 people, 61% feel that the president is doing an acceptable job. We are interested in the population proportion of people who feel the president is doing an acceptable job.

What is the point estimate for the population proportion?
a) 0.61
b) 1,200
c) 0.39
d) 61%

Answer 1

The point estimate for the population proportion is 0.61 or 61% (option d).

Step-by-step explanation:

The point estimate for the population proportion is 0.61 or 61% (option d).

To calculate the point estimate, we use the percentage from the survey as the estimate for the population proportion. In this case, the survey found that 61% of the 1,200 people surveyed feel that the president is doing an acceptable job, so the point estimate is 0.61 or 61%.
