Paul Col 260219493 Bio 206 9/27 Module II assignment 1. In order to obtain random samples, the table of random digits in the lab manual was used to choose numbers. For each sample, one extra number was chosen as to not use the first subjective number chosen. For the 30 number samples, rather than choosing 30 samples to use, 7 and 22 samples were chosen instead for the 1997 and 2000 samples (respectively), and those numbers were discarded from the sample, and the remaining were used. ash 1997 (mm) ash 1997(mm) ash 2000 (mm) ash 2000 (mm) 48.5 45 51.1 48.1 50.6 47.2 52.9 49.7 50.7 48.9 52.9 52 52.9 50.6 53.9 52.9 52.9 50.7 56.9 53.9 56.2 52.9 58.9 54.7 56.2 53.9 59.6 55.8 57.4 54.7 60.4 56.2 58.4 54.7 61.3 56.9 59.9 55 62.3 57.4 61.5 56.2 655 58.2 63 56.8 67.4 59.6 68 57 70.7 60 68.7 57.4 75 61.1 75.7 58.4 77.8 61.3 59.5 62 59.5 62.7 61 62.8 61.5 64 62.2 65.5 62.2 66.6 63 67.1 63.1 67.8 63.6 69.9 64.2 69.9 67.2 71.1 68 73.7 68.7 75 68.9 83.2 73.9 83.3

This makes perfect sense statistically, because the greater the sample, the more evenly distributed the results will be and the less the off-centered marks will affect the overall distribution. Other than the 15 tree sample in year 2000, these results meet the statistical expectations of the given data. 3.
