Question 4: Assume a randomly selected American family owns two cars. We know that each of the two cars – both the older car and the newer car – was manufactured in the U.S, Europe or Asia. Further assume that the family is equal likely to purchase any of the three types of cars, and the purchases of each of the cars are independent.

Note we use the following notation: U.S.-Europe indicates an outcome where the older car was manufactured in the U.S., and the newer car was manufactured in Europe.

Question 4a:

How many outcomes are there from this random experiment? (your answer should be an integer)

Question 4b:

What is NOT an event from this random experiment?

Group of answer choices

The family only owns one car.

Neither of the car is made in U.S.

At least one of the car is foreign (i.e not made in U.S.).

Both of the cars are foreign (i.e. not made in U.S.).

Question 4c:

How many outcomes are contained in the event that one car is made in U.S. and the other is foreign (i.e. not made in U.S.)? (your answer should be an integer)

Question 4e:

What is the probability that at least one car is European? (3 decimal places)

Expert Solution

note: in case of 4e, possible favourable cases are U.S - Europe , Europe - U.S ,Europe -Asia ,Asia - Europe and Europe -Europe .

American and Japanese workers can each produce 4 cars a year. An American worker can produce 10 tons of grain a year, whereas a Japanese worker can produce 5 tons of grain a year. To keep things simple, assume that each country has 100 million workers. Construct a world production possibilities frontier, assuming our world consists of only the U.S. and Japan. 5.1 What is the maximum amount of grain our world could consume if the world wished to consume...

A family has 4 children. Assume that each child is as likely to be a boy as it is to be a girl.

A family has 4 children. Assume that each child is as likely to be a boy as it is to be a girl. Find the probability that the family has 4 girls if it is known the family has at least one girl.

Students at a college randomly selected 217 student cars and found that they had ages with a mean of 7.89 years and a standard deviation of 3.67 years. They also randomly selected 152 faculty cars and found that they had ages with a mean of 5399 years and a standard deviation of 3.65 years. a) Using a 0.05 significance level, are student cars older than faculty cars? List: Define the parameters u1 and u2 Null and Alternative Hypothesis P-value Initial...

The probability that a randomly selected person is left-handed is 0.1. Suppose we are to randomly select 10 people. Let X be the number of people selected out of the 10 that are left-handed. Find the following probabilities: (a) P(X = 2) = (b) P(X ≤ 2) = (c) P(X > 2) =

Question 1 A Japanese firm manufactures cars in the US. Assume that each car sells for $20,000 to a consumer in the US. Also assume that on each car the Japanese manufacturer earns $2000 in profits and remits those to the holding company in Japan. Assume that the car is manufactured with US made parts only. What is the contribution of each car to the US GNP? $ 18,000 $20,000 $22,000 $2,000 Question 2 A Japanese firm manufactures cars in...

16. A sociologist surveys 50 randomly selected citizens in each of two countries to compare the mean number of hours of volunteer work done by adults in each. Among the 50 inhabitants of Lilliput, the mean hours of volunteer work per year was 52, with standard deviation 11.8. Among the 50 inhabitants of Blefuscu, the mean number of hours of volunteer work per year was 37, with standard deviation 7.2. Construct the 99% confidence interval for the difference in mean...

Randomly selected 8080 student cars have ages with a mean of 88 years and a standard deviation of 3.6 years, while randomly selected 9595 faculty cars have ages with a mean of 5.4 years and a standard deviation of 3.7 years. 1. Use a 0.03 significance level to test the claim that student cars are older than faculty cars. The test statistic is The critical value is Is there sufficient evidence to support the claim that student cars are older than...
