In an exercise class, participants are timed running a mile. The times (in minutes) are summarized in the table below, but some values are missing. (a) Fill in the table and draw the corresponding histogram. If you can't figure out the table, just put in anything and draw a histogram. More than one answer may be possible. Time Percent Height of bar 10 20 25 5-6 6-7 7-8 8-10 10-15 15 (b) Assuming that the percent in each bar is spread evenly for every interval, find the 45th percentile as accurately as possible. (c) Do you think the percent of people who took an above average amount of time is less than 50%, about 50%, or more than 50%? Explain briefly (one line is OK).
