Calculate the sample proportion (198 yes responses out of 316).

We want to test against a sample size of n = 2200 daily passengers.
In order to use the normal distribution, we should satisfy

2200*0.6266 = 1378.5
2200*(1-0.6266) = 821.5
We may use the normal distribution.
Let us use a 95% confidence interval.
The estimate for the population proportion is

where z* = 1.96 at the 95% confidence level.

Therefore
p = 0.6266 +/-0.0202 = (0.6064, 0.6468)
Answer:
At the 95% confidence level, about 60% to 64% of regular passengers will buy snacks on the train.
A leverage by is one where there is.
Answer: B.brand name

Answer:
B) False
Explanation:
Under the cost benefit analysis a statement is prepared in order to compute the financial aspects of the transaction.
This clearly provides for the estimate to be made towards all the transactions.
But there is a problem in such analysis that exact estimate or even nearby estimate in terms of amount is not feasible to be computed of benefits and cost as well.
And significantly all the benefits can not be traced monetarily.
