Answer:
The standard error of a proportion p in a sample of size n is given by: 
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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 a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation
In this question:
The standard error of a proportion p in a sample of size n is given by:
Answer:
Jim's path is the critical path on this activity graph.
Step-by-step explanation:
Critical Path:
Critical path is the the longest path in the project task paths. It shows the least amount of time in which project can be completed. It can be find by looking at the longest path in the network diagram of the project; not in term of nodes or activities instead in term of days.
In given case:
Path 1 Bill task's total duration= 6 days
Path 2 Jim's task's total duration= 17 days
Path 3 Betty task's total duration= 7 days
Path 4 Cynthia task's total duration= 14 days
Hence the longest path i.e. critical path is of Jim's activity path !
