A rare form of malignant tumor occurs in 11 children in a​ million, so its probability is 0.000011. Four cases of this tumor occurred in a certain​ town, which had 15,359 children.

a. Assuming that this tumor occurs as​ usual, find the mean number of cases in groups of 15,359 children.

b. Using the unrounded mean from part ​(a​) ,find the probability that the number of tumor cases in a group of 15,359 children is 0 or 1.

c. What is the probability of more than one​ case?

d. Does the cluster of four cases appear to be attributable to random​ chance? Why or why​ not?

A city government is considering two types of town-dump sanitary systems. Design A requires an initial outlay of $260,000 with annual operating and maintenance costs of $48,000 for the next 17 years. Design B calls for an investment of $160,000 with annual operating and maintenance costs of $67,000 per year for the next 17 years. Fee collections from the residents for both designs would be $75,000 per year. The interest rate is 5%, and no salvage value is associated with either system. In order to determine which system should be selected, calculate the incremental profitability index.

1. Utilizing the data shown in the contingency table 1 below, determine whether the relationship between types of residential area and gun ownership is statistically significant. Once you have arrived at an answer for each question, please write a sentence or two interpreting the results, you may want to round the decimals to the nearest whole number (70 pts.).

A single-lane bridge connects village A to village B. Farmers in the two villages use this bridge to deliver their products to the neighboring town. The bridge can become deadlocked if a farmer from village A and a farmer from village B get on the bridge at the same time. Using semaphores and/or mutex locks (do not be concerned about starvation) implement your solution in Java. In particular, represent village A and village B farmers as separate threads. Once a farmer is on the bridge, the associated thread will sleep for a random period of time, representing traveling across the bridge.
