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 0.039 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. (a) Identify the claim and state H, and Ha. Ho: На (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Find the critical value(s) and identify the rejection region(s). The critical value(s) is/are to = |. (Use a comma to separate answers as needed. Round to two decimal places as needed.)
