Test a claim that the mean amount of lead in the air in U.S. cities is less than 0.036 microgram per cubic meter. It was found that the mean amount of lead in the air for
the random sample of 54 U.S. cities is 0.037 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.
