1. During a given year, the following activities occur in a simple economy consisting of a miller and a baker The miller pays his workers $ 250,000 to mill 120 tons of flour. The flour is then sold to a baker for $ 530,000. The baker pays his workers 340,000 to make 750,000 loaves of bread, which she then sells directly to consumers for $ 1,000,000. a. Using the "final goods" approach, what is the GDP in this economy? b....

A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. a. What is the distribution for the weights of one 25-pound lifting weight? What is the mean and standard deviation? b. What is the distribution for the mean weight of 100 25-pound lifting weights? c. Find the probability that the mean actual...
