A dealer in recycled paper places empty trailers at various sites. The trailers are gradually filled by individuals who bring in old newspapers and magazines, and are picked up on several schedules. One such schedule involves pickup every second week. This schedule is desirable if the average amount of recycled paper is more than 1,600 cubic feet per 2-week period. The dealer’s records for eighteen 2-week periods show the following volumes (in cubic feet) at a particular site CubicFeet1,6601,5701,8201,7001,5901,9001,4401,8001,7301,7701,6802,0101,7501,5801,7201,6201,9001,690 Is there enough evidence to suggest that two-week pick-up schedule is desirable? Use 5% significance level. Clearly state the 6 steps of the hypothesis test you do and show all your work. NOTE: Since you have the data make sure to check if the the conditions for the above test are satisfied.

The density of pure iron is 7.874 g/cm.Apiece of steel made of pure iron and other types of iron is in the shape of a rectangular pyramid. The rectangular pyramid has a base edge length of 4 cm, a base edge width of 9 cm, a height of 5 cm, and a mass of 425 g. What is the difference between the density of pure iron and the density of the steel rectangular pyramid? Round your answer to the nearest thousandth. Type your answer.

An excavation company has been contracted to supply 10 million cubic feet (cu. ft.) of dirtto a construction site. The company uses a bulldozer to collect dirt, which is then moved by adump truck to the construction site. It costs the company $100 per hour to use the bulldozer,and it rents dump trucks at a rate of $40 per hour per truck. Each dump truck can hold 1,000cu. ft. of dirt, and it takes an average of 12 minutes for the bulldozer to load a dump truckwith dirt. It takes an average of five minutes for a fully loaded dump truck to deliver the dirtto the construction site and returns to the bulldozer for another load.Assume that the time to load a dump truck and the time for a dump truck to deliver the dirtto the construction site and return to the bulldozer follow exponential distributions. Moreover,a usual trip of the truck involves load with dirt, deliver the dirt, return to the bulldozer whereit joins a queue for another load of dirt.Then, determine the most appropriate…
