Test a claim that the mean amount of lead in the air in U.S. cities is less than 0.034 microgram per cubic meter. It was found that the mean amount of lead in the air for the random sample of 57 U.S. cities is 0.039 microgram per cubic meter and the standard deviation is 0.069 microgram per cubic meter. At a = 0.01, can the claim be supported? Complete parts (a) through (e) below. Assume the population is normally distributed. ...... (a) Identify the claim and state Ho and Ha. Ho: H: D (Type integers or decimals. Do not round.) The claim is the hypothesis.
