Test a claim that the mean amount of carbon monoxide in the air in U.S cities is less than 2.33 parts per million. It was found that the mean amount of carbon monoxide in the air for the random sample of 63 cities is 2.38 parts per millionband the standard deviation is 2.12 parts per million. At a= 0.01, can the claim be supported? Assume population is normally distributed. i) Identify the claim and state Ho and Ha ii) Find the critical value(s) and identify the rejection region(s). iii) Find the standardized test statistic, t. iv) Decide wheter to reject or fail to reject the null hypothesis. v) Interpret the decision in the context if the original claim.
