### Predicting Economic Trends Through Demographic AnalysisBy predicting fertility and divorce rates as well as lifestyle changes, demographers attempt to forecast the economy during the next decade and beyond. This involves predicting which industries will flourish and which will falter. The following table provides a distribution of age groups in the U.S. for the year 2030:#### Age Distribution Table for 2030| Age Group | Relative Frequency ||---------------|--------------------|| 0-9.5 | 0.12 || 9.5-19.5 | 0.14 || 19.5-29.5 | k || 29.5-39.5 | 0.16 || 39.5-49.5 | 0.16 || 49.5-59.5 | 0.12 || 59.5-69.5 | 0.08 || 69.5-79.5 | 0.06 || 79.5-89.5 | 0.03 |**Task:**a) Find the value of k.**Solution:**To find the value of k, we use the fact that the sum of all the relative frequencies must equal 1. Summing the given relative frequencies:\[0.12 + 0.14 + k + 0.16 + 0.16 + 0.12 + 0.08 + 0.06 + 0.03 = 1\]Combining the known values:\[0.87 + k = 1\]Solving for k:\[k = 1 - 0.87 = 0.13\]Thus, the value of $ k $ is $ 0.13 $.This information helps predict economic trends by understanding the distribution of different age groups within the population.

16 In 1970, the U.S. Armed Services instituted a lottery as a random selection process when 19- year old males were drafted into service. Each of the possible 366 possible birth dates was placed in a separate capsule and each capsule was placed in a large plastic drum. Those with the lowest lottery numbers were drafted before others. For example, the May 9th was 176. This meant that there would be 175 groups of males born on other days drafted before those who had been born on May 9th. The scatter plot below shows the median draft eligible number for each month of the year. The line that connects the points is sometimes called a median trace line. Which one of the following statement is TRUE? * Median Trace of Draft Lottery Numbers 240 220- 200- 180- 160 140 120 100 F M. A Median Draft Number to
