The U.S. Environmental Protection Agency (EPA) monitors levels of pollutants in the air for cities across the country. Ozone pollution levels are measured using a 500 point scale; lower scores indicate little health risk, and higher 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 2 City 3 City 4 Jan S 17 20 18 14 Jan 17 23 31 22 30 Jan 18 25 22 21 Jan 31 20 36 28 35 Feb 1 27 31 28 24 Feb 6 26 32 31 25 Feb 14 30 24 19 25 Feb 17 31 32 28 28 Feb 20 33 35 35 34 Feb 29 20 41 42 21 Use 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 Ho: Not all the population means are equal. Hai H1 = H2 = M3 = H4 O Ho: H1 = H2 # H3 * H4 Ha: H1 = H2 = M3 = H4 O Ho: At least two of the population means are equal. H: At least two of the population means are different. O Ho: H1 = H2 = H3 = H4 Ha: Not all the population means are equal. O Ho: My = H2 = H3 = H4 Hai H1 * H2 # #3 * H4 X Find the value of the test statistic. (Round your answer to two decimal places.) 1.40 XFind the p-value. (Round your answer to three decimal places.) p-value = 0.258 1x State your conclusion. O Reject Ho. There is 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 sufficient evidence to conclude that there is a significant difference 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. Do not reject H. There is not sufficient evidence to conclude that there is a significant difference in the mean peak ozone level among the four cities
