W ONLINE-GE 2022 01/31 C1-M Tutorial Exercise Zane is examining two studies involving how different generations classify specified items as either luxuries or necessities. In the first study, generation A is defined to be people ages 15-26. The second study defined generation A to be people ages 18-29. Zane notices that the first study was conducted in 2005 while the second one was conducted in 2008. (a) Are the two studies inconsistent in their description of generation A? (b) According to the 2005 study, what are the birth years of generation A? Step 1 (a) Are the two studies inconsistent in their description of generation A? If the studies are inconsistent, it means that at least some of the age group from the first study will not be included in the second study, or some of the age group from the second study will not be in the first study. Therefore, to determine if the two studies are inconsistent in their description of generation A we must compare the age groups from the two studies to see if either one includes people not included in the other study. In other words, we need to determine if the age ranges match up exactly when the year of the study is taken in to consideration. In the first study from 2005, generation A is defined to be people ages 15-26. Three years later, in 2008, the second study was published and defined generation A to be people ages ages 18-29. First we examine the low end of the age ranges. We note that someone who was 15 years old in 2005 would be 18| 18 years old in 2008. Now we examine the high end of the age ranges. We note that someone who was 26 years old in 2005 would be 29 29 years old in 2008. The low and high ends of the age ranges for the two studies match match when the year the studies were published is taken in to consideration. Therefore, the studies are not are not inconsistent. Step 2 (b) According to the 2005 study, what are the birth years of generation A? In the 2005 study, we notice that the oldest people in generation A are 26 years old. Therefore, these oldest people were born years before 2005, which means they were born in In the same study, we notice that the youngest people in generation A are 15 years old. Therefore, these youngest people were born years before 2005, which means they were born in Submit Skip (you cannot come back) Need Help? Read It
