Problem #1 ( 12.5 pts). To test the durability of a new paint for white center lines, a highway department painted test strips across heavily traveled roads in fourteen different locations, and electronic counters showed that they deteriorated after having been crossed by 12.58 14.26 16.78 13.65 11.5 10.83 12.64 13.37 16.20 14.96 13.5 13.1 15.66 and 14.87 million cars. Construct a 95% confidence interval for the average amount of traffic (car crossings) this paint can withstand before it deteriorates.
