The Xhang Corporation operates five clothing suppliers in China to provide merchandise for Nike. Nike recently sought information from the five plants. One variable for which data was collected was the total money (in U.S. Dollars) the company spent on medical support for its employees in the first three months of the year. Data on number of employees at the plants are shown. These data are as follows: Medical $7,400 $14,400 $12,300 $6,200 $3,100 Employees 123 402 256 109 67 (a). Compute the weighted mean medical payment for these five plants using number of employees as the weights. (b). Explain why Nike would desire that a weighted be computed in this situation rather than a simple numeric average Answer all questions

Jack is a discus thrower and hopes to make it to the Olympics some day. He has researched the distance (in meters) of each men's gold medal discus throw from the Olympics from 1920 to 1964. Below is the equation of the line of best fit Jack found. y=0.34x+44.63y=0.34x+44.63 When calculating his line of best fit, Jack let x represent the number of years since 1920 (so x=0 represents 1920 and x=4 represents 1924). Using the line of best fit, estimate the distance Jack should be able to throw in order to be able to win the 2020 Olympics.
How does the speed of a runner vary over the course of a marathon (a distance of 42.195 km)? Consider determining both the time to run the first 5 km and the time to run between the 35-km and 40-km points, and then subtracting the former time from the latter time. A positive value of this difference corresponds to a runner slowing down toward the end of the race. The accompanying histogram is based on times of runners who participated in several different Japanese marathons (“Factors AffectingRunners' Marathon Performance,” Chance, Fall, 1993: 24-30). What are some interesting features of this histogram? What is a typical difference value? Roughly what proportion of the runners ran the late distance more quickly than the early distance? Histogram for Exercise 22
