8) A closer examination of the records of the air samples in Example 3 reveals that each line of the data actually represents readings on the same day: 2.92 and 1.84 are from day 1, and so forth. Since this affects the validity of the results obtained in Example 10, reanalyze. (Use a=0.05.) Area A 2.92 1.88 5.35 3.81 4.69 4.86 5.81 5.55 Area B 1.84 0.95 4.26 3.18 3.44 3.69 4.95 4.47
