Exercise 20-29 Algo Random samples were drawn from three Independent populations. The accompanying data file shows the results. Use Table 3. Click here for the Excel Data File a. Specify the competing hypotheses to test whether some differences exist between the medians. He: m2 m2 = 3; Ha Not all population medians are equal. OH: 1 2 2 2 M3; HA: All population medians are equal. He: m = m2 m3; HA: All population medians are equal. b. Calculate the value of the test statistic H. (Round final answer to 3 decimal places.) Test statistic
c-1. Find the p-value. 0.05 Picture p-value < 0.10 p-value Picture 0.10 p-value < 0.01 0.01 Picture p-value < 0.025 0.025 Picture p-value < 0.05 c-2. Can we conclude some medians diffe No, since we do not reject Ho. No, since we reject Hg. Yes, since we do not reject He- Yes, since we reject Hg.
