Question 176611: In Dallas, some fire trucks were painted yello( instead of red) to heighten their visibility. During a test period, the fleeet of red fire trucks made l53,348 runs and had 20 accidents, while the fleet of yellow fire trucks mad l5,035 runs and had 4 accidents.Did the yellow trucks have a significantly lower accident rate?

looks like they were significantly higher.
rate for red trucks was 20/153348
rate for yellow trucks was 4/15035
let x = rate for red trucks / rate for yellow trucks
x = (20/153348)/(4/15035)
x = 0.490224848058
this means that the rate of accidents for the red trucks was a little less than 1/2 times the rate of accidents for the yellow trucks.

conversely,
let y = rate for yellow trucks / rate for red trucks
y = (4/15035)/(20/153348)
y = 2.039880279348
this means that the rate of accidents for the yellow trucks was a little more than 2 times the rate of accidents for the red trucks
