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.

D. Less than that of its competitors.
Explanation:
Personally, I believe that GM is an extremely spoiled child that refuses to assume responsibility for its continuous and never ending mistakes. GM has either filed for bankruptcy or threatened to do so twice in the last 30 years or so, and every time the US government has to bail them out. But GM keeps doing things wrong.
It doesn't matter if you like their cars or not, GM is terribly managed. No other company in US history has received so much financial aid from the government and continued to lose money and work inefficiently. The problem is that whenever things go wrong, stockholders lose their money but the executives keep getting tens of millions of dollars. If a company is managed in such a disastrous way, their top management shouldn't get paid that much.
A car factory costs a lot of money, and not using it efficiently is outrageous considering GM's history. If they had never received a cent from the government, then its only their problem. But the government lost $11.2 billion on GM's last bailout. During the 1980s GM lobbied fro the government to impose import quotas on Japanese cars because they were better cars and GM couldn't compete against them. So whenever they do things wrong, big brother has to help them. During the last couple of years GM had to sell most of its foreign operations in order to get cash, and you generally do not make money by selling your assets.
