03.(13) A study was conducted to examine the number of rain days in July. Three cities A, B, G are selected, and the number of rain days in July from year 2001 - 2005 were recorded, Assume the samples are Independent. A: 3, 5, 4, 5. 6 8: 6. 8, 7, 9, 10 C: 3, 5, 2, 1, 6 1(7). Is there any evidence to suggest that at least two cities mean number of rain days in July are different? Use a = 0.05. 2(6). Calculate the 95% Bonferroni confidence intervals for /j - /42, and identify if these pair has significant difference. Note: to.0093 (12) = 2.7816
