Answer: This result is not unusual.
So, it does not seem that the claimed rate of 16% is wrong
Step-by-step explanation:
Since we have given that
n = 100
p = 0.16
q = 1 - 0.16 = 0.84
So, Mean would be
and standard deviation would be
Now, if there are 19 green,
so, we will check how it is far,
Since it is 0.817 standard deviations away from the mean.
So, this result is not unusual.
So, it does not seem that the claimed rate of 16% is wrong.
