Answer: Even is not unusual.
Step-by-step explanation:
Given:
P = 0.10
n = 1200
x = 132
1. Sample of proportion ( ˆp ) = x/n
= 132/1200
= 0.11
2. Z = ˆp - p / √p ( 1 - p )/ n
= 0.11 - 0.10 / √0.10 ( 1 - 0.10 ) / 132
= 0.01 / 0.02611
= 0.3829
3. Probability
P ( ≥ 132 ) = P( Z > 1.50 ) = 1 - P( Z > 1.50 )
= 1 - 0.9332
= 0.0668
The probability is higher than (0.05). Which makes the event unusual, therefore there is no enough evidence which suggest that the number of Americans who are afraid to fly has increased.
