Problem 1 - Find a general expression for the estimate of the parameter beta in an exponential distribution and its 90% confidence interval, assuming N number of observations from the population.
Problem 2 - A car dealer sells a specific model at a rate of 4 units a day. The manager determined that the sales follow a Poisson distribution.
A) If the dealer has a stock of 4 cars of this model in a particular morning, what is the probability that the dealer will run out of stock that day?
B) What is the probability that they will run out of stock if they have a stock of 6 cars that morning?
Problem 3 - Download the file "Data_100.csv" attached. Using the data in the file, create a box plot. Also create a histogram by using the fact that the number of datapoints within a range is a good representation of the probability the distribution would be within that range. For example, if there are 7 datapoints between 0 and 5, P(0 ≤ X ≤ 5) ∼= 0.07. Divide the whole range into 10 disjoint adjacent equi-width intervals.

At a roadside vehicle safety checkpoint, officials plan to randomly select 50 cars for which this is the recommended tire pressure and measure the actual tire.
The average weight of 40 randomly selected minivans was 4150 pounds. The standard deviation was 480 pounds. Find the 99% confidence interval of the true weight of the minivans.
A company is filling bags of rock salt to a level of 50 pounds. It believes that all bags are filled correctly, but would like to use a hypothesis test with an alpha of 0.05 to check this belief.
Assume the distribution of amounts purchased follows the normal distribution. For a sample of 50 customers, answer the following questions. What is the likelihood the sample mean is at least $25.00?
CCI is unable to adjust the mean of the filling process. However, it is able to adjust the standard deviation of the filling process. What would the standard deviation need to be so that no more than 2% of all filled bags weigh more than 52 kilogra..
