Based on the random assessment of four years, the Mean Net Production and Standard Deviation for a grassland are 120 gC/m2/year and 4 gC/m2/year, respectively. The 90% confidence interval around this estimate (t at 10% level of significance for df 3 is 2.353) is
1
120 ± 8.613 gC/m2/year
2
120 ± 4.706 gC/m2/year
3
120 ± 2.353 gC/m2/year
4
120 ± 9.412 gC/m2/year
