According to the 2012 PPG Industries and DuPont annual automotive paint trend data, 19% of North Americans prefer the color black. Assuming that all areas of North America are uniformly distributed, then we can say that around 19% of all cars parked in the CCSF parking lot are painted black.

1) We included 2 rows, counted 56 cars in total and then we found 20 black cars. 2) Our percentage was 36%.

Based on the type cars we observed at CCSF, we noticed students preferred (updated "new" cars) so these are coming more in color then dull colors (Black, Grayy, White). it seems that CSSF faculty they have more old fashioned cars, which the colors of there cars would be...(White, Black, Gray). To give the estimate of how many Black cars are here in the CCSF parking lots, our estimation would be around 35%-40%.

1) We counted the number of cars in an area and the total number of black cars. We did this with two different areas in the parking lot around the MUB building. From that, we calculated two percentages and found the average of the two.

The total cars counted was 162 and the total number of black cars counted was 27.

2) 16.7%  of the cars were black.

According to Wikipedia, 19% of cars in North America are painted black.  We sampled  73 cars in the parking lot, and 17 were painted black (23%).

Final answer: 21%

# data[].attributes.body
In general, majority of people have black or white cars. There is a small percentage with colored cars, from typical experiences and what we see in the CCSF parking lot. Then we just estimated that about 40% are black, 40% white, and 20% colored.

1.We narrowed it down to one small parking lot in front of the mub building.

2.  A total of 30 cars were parked in the parking lot and 8 of them were black.
