McMahon and Associates, an engineering firm, counted 300 cars passing through an intersection. The observations showed that 175 of the cars were traveling in the northbound/southbound lanes and 55 of those turned left at the intersection. The remaining 125 cars were traveling in the eastbound/westbound lanes and 30 of those turned left at the intersection. Use the count data to estimate the probability that a randomly chosen car arriving at the intersection is traveling in the northbound/southbound lanes or is making a left turn.

A traffic engineer believes that the number of cars passing through a certain intersection between 2 and 6 pm on weekdays follows a normal distribution with mean 750 and standard deviation 100. A new highway is opened, and it is hypothesized that the number or cars passing through the intersection should decrease as a result. A sample of 15 weekdays is taken, and the mean number of cars passing through the intersection is 710. Decide whether this reduction in traffic...
