Please don't provide hand writtin solution... City R is a large city with 4 million residents, and City S is a smaller city with 0.25 million residents. Researchers believe that the proportion of City S residents who regularly ride bicycles is between 10 percent and 25percent and the proportion of City R residents who regularly ride bicycles is between 20 percent and 50 percent.Suppose two independent random samples of residents from each city will be taken and the proportion of residents who ride bicycles is recorded. Based on the population proportions of residents who regularly ridebicycles, which of the following sample sizes is large enough to guarantee that the sampling distribution of the difference in sample proportions will be approximately normal?B(C)DE30 in City R and 30 in City S30 in City R and 60 in City S60 in City R and 30 in City S50 in City R and 100 in City S100 in City R and 50 in City S

Clinton Bay is famous for its wild salmon, one of the most spectacular seafood products in the world. However, due to years of heavy fishing, some researchers believe that the average size of wild salmon is getting smaller. To ensure sustainability of the salmon population, the government of Clinton Bay only allows salmon with a length of 80 cm or longer to be kept. In other words, any salmon caught that are shorter than 80cm will need to be released back to the sea. An international fishing company is considering expanding their business into Clinton Bay, but they are concerned about whether they can harvest enough large salmon to make their desired profit. Based on information gathered from other fishing companies, 35% of the salmon caught at Clinton Bay are longer than 80 cm. They also know from a scientific report that the mean length of the salmon caught in the recent years is 72 cm, and the standard deviation of the lengths is 10 cm. ) Based on the reported mean and standard…
It's true — sand dunes in Colorado rival sand dunes of the Great Sahara Desert! The highest dunes at Great Sand Dunes National Monument can exceed the highest dunes in the Great Sahara, extending over 700 feet in height. However, like all sand dunes, they tend to move around in the wind. This can cause a bit of trouble for temporary structures located near the "escaping" dunes. Roads, parking lots, campgrounds, small buildings, trees, and other vegetation are destroyed when a sand dune moves in and takes over. Such dunes are called "escape dunes" in the sense that they move out of the main body of sand dunes and, by the force of nature (prevailing winds), take over whatever space they choose to occupy. In most cases, dune movement does not occur quickly. An escape dune can take years to relocate itself. Just how fast does an escape dune move? Let x be a random variable representing movement (in feet per year) of such sand dunes (measured from the crest of the dune). Let us assume that…

You are a package designer for Table Tennis Ball (Ping pong) Company. The company needs you to design a package to ship out the newest ping pong balls. You need to minimize the cost of the packaging material, while being aware of the uniqueness, stack ability and other non-monetary concerns. Packaging material will cost 0.005 cents per square centimeter. You will have to package 12 ping pong balls in your package, each with a diameter of 4 cm. Create 2 unique design proposals. One design must be a cuboid,and the second design cylinder . Calculate the surface area and volume of both designs cuboid and cylinder Cost of making the 2 packages. Pros and Cons of each design .pitch which package you recommend for the company to make cuboid or cylinder .
