Test a claim that the mean amount of lead in the air in U.S. cities is less than 0.035 microgram per cubic meter. It was
found that the mean amount of lead in the air for the random sample of 55 U.S. cities is 0.038 microgram per cubic
meter and the standard deviation is 0.069 microgram per cubic meter. At a = 0.05, can the claim be supported?
Complete parts (a) through (e) below. Assume the population is normally distributed.
