Answer the following questions based on this data. Be sure to show all of your work for each question. 1. What was the Group A mean walking time? By what percent did YOU exceed or fall below the group A mean? Express your answer rounded to the nearest hundredth. 2. What was the Group B median walking time? By what percent did YOU exceed or fall below the group B median? Express your answer rounded to the nearest hundredth. 3. Let's suppose you want to draw a pie chart that shows information for the members of each group classified by a rating based on the amount of walking time. There will be 4 categories: excellent, very good, good, needs improvement. The Needs Improvement category is for the percentage of group members who walked for less than 600 minutes. Which group [A or B] has the larger percentage of members in the Needs Improvement category? What is that percentage? Express your answer to the nearest hundredth. 4. One other way to look at the data is by percentiles. What was your percentile rank in each group? Round the percentiles to the nearest whole number.
