← 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 63 cities is 2.41 parts per million and the standard deviation is 2.09 parts per million. At a=0.10, can the claim be supported? Complete parts (a) through (e) below. Assume the population is normally distributed. STE (a) Identify the claim and state Ho and H₂. Which of the following correctly states Ho and H₂? Ho: P 2 2.34 H₂: μ 2.34 (Type integers or decimals. Do not round.) The claim is the alternative hypothesis. (b) Use technology to find the critical value(s) and identify the rejection region(s).
