dangerous day on Maple Street?
Sarah was calculating the speeds (mph) of vehicles travelling down Maple Street on two separate days at
9 am for an hour. Below is the data she collected.
Wednesday's Speeds: 34,28,24,17,39,44,64,33,27,21,38,40,60,30,25,37,30,25,35,30

1. Create a frequency table for each day. Make sure you look at both days when setting the intervals
for your frequency table. Remember that you need to use common intervals for both days to tally
the frequency.

2. Create a histogram with appropriate labels for each day using the frequency tables you created in
#1.
3. What do you notice about the two histograms? Consider the following questions: Are there any
patterns in the speed distribution? Does one day look worse than the other?
The following chart shows the percentage of the U.S. discretionary budget allocated to education from 2003 to 2009 (t = 3 represents the start of 2003).
A bar graph titled "Percentage of U.S. budget on education" has a horizontal t-axis labeled "Year since 2000" and a vertical axis labeled "Percentage". The bar graph has 7 bars. Each bar is associated with a label and an approximate value as listed below.
3: 6.8%
4: 7%
5: 7%
6: 6.9%
7: 6.5%
8: 6.3%
9: 6.2%
