Solution :
Sample proportion is said to follow normal distribution if
(i) nπ ≥ 10 and (ii) n(1 - π) ≥ 10.
Only the values given in option (3) satisfies the both of the above two conditions. Hence, for n = 50, π = 0.50, the sample proportion safely be assumed to follow normal distribution.
None of the other options satisfies the both of the conditions.
Hence, third option is correct.
