The range of possible values best describes an estimate for the population parameter is (0.6, 0.9) option (B) is correct.
What are population and sample?
It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
The question is incomplete.
The complete question is:
If a sample proportion is 0.75, which range of possible values best describes an estimate for the population parameter?
- (0.6, 0.89)
- (0.6, 0.9)
- (0.7, 0.79)
- (0.75, 0.8)
We have:
If a sample proportion is 0.75.
From the first option:
(0.6, 0.89)
= (0.6+0.89)/2
= 0.745
From the second option:
(0.6, 0.9)
= (0.6+0.9)/2
= 0.75
From the third option:
(0.7, 0.79)
= (0.7+0.79)/2
= 0.745
From the fourth option:
(0.75, 0.8)
= (0.75+0.8)/2
= 0.775
Sample proportion = 0.75 and the range of possible values best describes an estimate for the population parameter is (0.6, 0.9).
Thus, the range of possible values best describes an estimate for the population parameter is (0.6, 0.9) option (B) is correct.
