Use the following information to answer the next eleven exercises. The age of cars in the staff parking lot of a suburban college is uniformly distributed from six months (0.5 years) to 9.5 years.
Considering only the cars less than 7.5 years old, find the probability that a randomly chosen car in the lot was less than four years old.
a. Sketch the graph, shade the area of interest.
b. Find the probability
According to the American Red Cross, about one out of nine people in the U.S. have Type B blood. Suppose the blood types of people arriving at a blood drive are independent. In this case, the number of Type B blood types that arrive roughly follows the Poisson distribution.
a. If people arrive, how many on average would be expected to have Type B blood?
b. What is the probability that over people out of these 100 have type B blood?
c. What is the probability that more than people arrive before a person with type B blood is found?
Use the following information to answer the next ten questions. The data that follow are the square footage (in feet squared) of homes
The sample mean and the sample standard deviation The distribution can be written as
Use the following information to answer the next eleven exercises. The age of cars in the staff parking lot of a suburban college is uniformly distributed from six months (0.5 years) to 9.5 years.
The distribution for is ______.
The data that follow are the number of passengers on 35 different charter fishing boats. The sample mean = 7.9 and the sample standard deviation = 4.33. The data follow a uniform distribution where all values between and including zero and 14 are equally likely. State the values of and . Write the distribution in proper notation, and calculate the theoretical mean and standard deviation.
