Sample proportion
We have to find the range of possible values which describes best an estimate for the population parameter.
Estimate for the population parameter
A.(0.55,0.6)
Difference between 0.55 and 0.55=0
Difference between 0.55 and 0.6=0.05
Difference between 0.55 and 0.55 is not equal to difference between 0.55 and 0.6.
Hence, option A is wrong.
B.(0.4,0.7)
Difference between 0.55 and 0.4=0.15
Difference between 0.55 and 0.7=0.15
Difference between 0.55 and 0.4 is equal to difference between 0.55 and 0.7.
Hence, option B is correct.
C. (0.4,0.69)
Difference between 0.55 and 0.4=0.15
Difference between 0.55 and 0.69=0.14
Difference between 0.55 and 0.4 is not equal to difference between 0.55 and 0.69.
Hence, option C is not correct.
D.(0.5,0.59)
Difference between 0.55 and 0.5=0.05
Difference between 0.55 and 0.59=0.04
Difference between 0.55 and 0.5 is not equal to difference between 0.55 and 0.59.
Hence, option D is not correct.
