Test a ciam 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 ot 62 cities is 2.38 parts per million and the standard deviation is 2.11 parts per million. At a = 0.10, can the claim be supported? Complete parts (a) through (e) below. Assume the population is normally distributed ()Find the standardized test stalistic, 1. The standardized test statistic is%3 0.19 (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. Fall to reject H, because the standardized test statistic is not in the rejection region. (e) Interpret the decision in the context of the original claim. There enough evidence at the % level of significance to the claim that the mean amount of carbon monoxide in the air in U.S. cities is parts per million. (Type integers or decimals. Do not round.)
