Answer:
a) 0.172 
b) 0.167 
c) 0.1404
Step-by-step explanation:
Margin of error, E = 
here,
p = probability of the event
n = sample size
a) n = 30
p = 10 ÷ 30 = 0.333 
Therefore,
E = 
= 2 × 0.0861
= 0.172 
b)  n = 30
p = 21 ÷ 30 = 0.7
Therefore,
E = 
= 2 × 0.0836 
= 0.167 
c) n = 30
p = 22 ÷ 50 = 0.44
Therefore,
E = 
= 2 × 0.0702
= 0.1404
