- The ages (in years)of 10,998 people (on foot or in a vehicle) stopped by police were analyzed and are described by the relative frequency histogram in the figure Some of the ages are less than 10 years or greater than 65 years, the bars for those ages would not be visible Complete parts (a) through (d)below. W: Click the icon to view the relative frequency histogram for the ages of people stopped by police. a. Describe the shape of the distribution. The distribution is unimodal and skewed right. What does it mean in this situation? A. It means that the ages of people stopped by police that are older than the 40th percentile are much more spread out than the ages of people stopped by police that are younger than the 60th percentile B. It means that the ages of people stopped by police that are older than the 50th percentle are much more spread out than the ages of people stopped by police that are younger than the 50th percentile. C. It means that the ages of people stopped by police that are younger than the 40th percentle are much more spread out than the ages of people stopped by police that are older than the 60th percentle. D. It means that the ages of people stopped by police that are younger than the 50th percentle are much more spread out than the ages of people stopped by police that are older than the 50th percentle. b. Estimate the proportion of people stopped by police who were at most 19 years of age. The proportion of people stopped by police who were at most 19 years of age is 0.28 (Type an integer or a decimal. Do not round.) C. From inspecting the histogram, a student says the result you found in part (b) is the correct proportion for any year. What would you tell the student? A. The proportion of people stopped by police who were under 20 years will be the same amount in other years, but this is not the correct proportion for people who were over 20 years. B. The proportion of people stopped by police who were under 20 years will be the same amount in other years, so this is correct C. The proportion of people stopped by police who were under 20 years will always be different from the amount in other years. D. It cannot be assumed that the proportion of people stopped by police who were under 20 years would be the same amount in other years. d. Identify which class contains the 50th percentle.which is a measure of the center. Choose the correct answer below and fill in the answer box(es) to complete your choice. (Type a whole number.) OA. The class that contains the 50th percentile is to years of age. OB. The class that contains the 50th percentle is years of ago.
