Answer:
C. The population must be normally distributed.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For us to apply the central limit theorem with a sample size of 14, the underlying population must be normally distributed.
So the correct answer is:
C. The population must be normally distributed.
We need 2880 person-hours and we have 12 people.
When we divide the work between them: 2880/12 = 240 hours required to complete.
I believe the Answer is A
60% is shaded because each box equals 10% and since 6 of them are shaded 10%*6= 60%
