Answer: p= 0.644
Step-by-step explanation:
We know that, the confidence interval for population proportion is given by :-
sample proportion(p) ± Margin of error(E)
Given confidence interval : (0.61,0.678)
i.e. p- E = 0.61 ... (i)
p+E = 0.678 ...(ii)
Adding (i) and (ii), we get
2p = 1.288
p= 0.644
From (ii),
E= 0.678-0.644
E= 34
Hence, the value of p = 0.644
