le 12.1 A company manufacturing automobile tyres finds that tyre-life is normally distributedwith a mean of 40,000 km and standard deviation of 3,000 km. It is believed that a change in theproduction process will result in a better product and the company has developed a new tyre. A sampleof 100 new tyres has been selected. The company has found that the mean life of these new tyres is40,900 km. Can it be concluded that the new tyre is significantly better than the old one, using thesignificance level of 0.01?

In a study of exhaust emissions from school buses, the pollution intake by passengers was determined for a sample of nine school buses used in the Southern California Air Basin. The pollution intake is the amount of exhaust emissions, in grams per person, that would be inhaled while traveling on the bus during its usual 18-mile trip on congested freeways from South Central LA to a magnet school in West LA. Here are the amounts for the nine buses when driven with the windows open. 1.17 0.33 0.40 0.33 1.32 0.38 0.25 0.40 0.35 (a) Consider making a stemplot.
