Test a claim that the mean amount of carbon monoxide in the air in U.S. cities is less than 2.34 parts per million. It was found that the mean amount of carbon monoxide in the air for the random sample of 62 cities is 2.39 parts per million and the standard deviation is 2.11 parts per million. At a=0.01, can the claim be supported? Complete parts (a) through (e) below. Assume the population is normally distributed. GETED
