Answer:
You would expect for 35 people to have consumed alcoholic beverages.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they consumed alcoholic beverages, or they did not. The probability of a person having consumed alcoholic beverage is independent of any other person. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
We learned in Exercise 3.25 that about 70% of 18-20 year olds consumed alcoholic beverages in 2008.
This means that
We now consider a random sample of fifty 18-20 year olds.
This means that
How many people would you expect to have consumed alcoholic beverages
You would expect for 35 people to have consumed alcoholic beverages.
Traveling miles on this taxi costs
In fact, we spend 2.50 no matter what, and then we add 3.25 (i.e. the cost of a mile) multiplied by the number of miles.
This quantity has to be less than or equal to 61, so we have
Solving for , we start by subtracting 2.5 from both sides:
Then, we divide both sides by 3.25:
