Q #1

Driving under the influence of alcohol (DUI) is a serious offense. The following data give the ages of a random sample of 50 drivers arrested while driving under the influence of alcohol. This distribution is based on the age distribution of DUI arrests given in the Statistical Abstract of the United States (112th Edition). 26 (a) Make a stem-and-leaf display of the age distribution. (Use the tens digit as the stem and the ones digit as the leaf. Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.) Age of DUI Arrests (b) Make a frequency table using seven classes. Class Limits Class Boundaries Midpoint Frequency Relative Cumulative Frequency Frequency (c) Make a histogram showing class boundaries. 0.3 0.25 0.2 50 0.15 Frequency 0.1 0.05 TITTY 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 O Frequency O Age 0.3 0.25 0.2 ARE 0.15 CHNWPUIONALOHNOA Fre 0.1 0.05 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 O Frequency O Age0.3 Relative Frequency Relative Frequency 0.15 PHNWALION JOBIDOL 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 O Age O Age 0.3 0.25 0.2 20 0.15 Age 0.1 0.05 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 15.5 22.5 29.5 36.5 43.5 50.5 57.5 64.5 O Relative Frequency O Relative Frequency (e) Identify the shape of the distribution. O bimodal O skewed right O uniform O skewed left (f) Draw an ogive. (Graph each point and the closed line segments connecting the points to create your graph.) Graph Layers After you add an object to the graph you can use Graph Layers to view and edit its properties. Help[g) Discuss how this data might be used to price auto insurance for different age groups. O The data shows the highest prevalence of DUI arrests in 50-59 year olds, so this group may be priced higher to take this into account. O The data shows the highest prevalence of DUI arrests in 40-49 year olds, so this group may be priced higher to take this into account. O The data shows the highest prevalence of DUI arrests in 20-29 year olds, so this group may be priced higher to take this into account. O The data shows the highest prevalence of DUI arrests in 60-69 year olds, so this group may be priced higher to take this into account. O The data shows the highest prevalence of DUI arrests in 30-39 year olds, so this group may be priced higher to take this into account. Submit Answer Question 1 of 10 View Next
