The U.S. Environmental Protection Agency (EPA) monitors levels of pollutants in the air for cities across the a 500 p s indicate little health risk, an scores indicate greater health risk. Suppose the following data show the peak levels of ozone pollution in four cities for 10 dates from last year. City Date City 1 City Z City 3 City 4 Jan 9 18 19 18 14 an 17 23 31 22 30 an 18 19 25 22 21 Jan 31 29 36 26 35 Feb 1 28 31 24 eb 6 26 31 31 25 eb 14 31 24 10 eb 17 31 31 2B 28 feb 20 33 35 35 34 Feb 29 20 42 42 21 a = 0.05 to test for any significant difference in the mean peak ozone levels among the four cities. State the null and alternative hypotheses. O H: Not all the population means are equal. He: H1 = H2 = M3 = H4 OH: H1 = M2 = M3 = HA H : A = H2 = M3 = H4 OHp: H, = H2 = M3 = H4 He : P ] = H2 = #3 = M4 O Ho: At least two of the population means are equal. H: At least two of the population means are different. OH: "] = #2 = M3 = P4 H : Not all the population means are equal. Find the value of the test statistic. (Round your answer to two decimal places.) 4.51 1X Find the p-value. (Round your answer to three decimal places.) p-value = 0.008 State your conclusion. Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference in the mean peak ozone level among the four cities. O Do not reject Ho- There is s in the mean peak ozone level among the four cities. O Reject Ho- There is not sufficient evidence to conclude that there is a significant difference in the mean peak ozone level among the four cities. Reject Hy- There is sufficient evide is a significant difference in the mean peak ozone level among the four cities
