Table 2.1. woodlot (identified by numbers), woodlot area (in hectares), number of traps, number of gophers in the first sample, and number of gophers in the second sample for 10 woodlots in blue earth county, mn. woodlot area of woodlot (hectares) number of gophers in first sample number of gophers in second sample w1 3.1 10 7 w2 5.6 12 9 w3 2.9 19 17 w4 11.2 24 18 w5 9.9 28 20 w6 3.0 7 4 w7 13.0 22 15 w8 8.6 8 6 w9 18.8 28 25 w10 8.3 30 25 calculate population estimates and enter the data in worksheet 2.1. calculate the density (number of gophers per hectare) for each of the woodlots and enter these data. how many significant decimal points should you report for the population size estimate and the density? (think about the units for each measurement.) (1/2 point each cell = 10 pts for the table) worksheet 2.1. population size estimates and densities for gophers in 10 blue earth county, mn woodlots. woodlot w1 w2 w3 w4 w5 w6 w7 w8 w9 w10 mean moran-zippin estimate (n) woodlot area (ha) density (n/ha) 1. what is the mean density of gophers in the 10 woodlots in blue earth county, mn? consider carefully how many significant figures to report. (2 pts) 2. as a scientist it is your job to analyze your results carefully. do any of the data you calculated appear inconsistent? (compare all your calculated values.) how does including these data affect your calculation of mean gopher density? what would you do and/or what might you say in your report about this inconsistency? (4 pts) 3.the dnr would like you to estimate the total number of gophers in blue earth county woodlots. without setting any more traps, what additional information would you need and how might you calculate that estimate? (4 pts)
