Will give brainlist...if you steal points only will report you For each of 18 preserved cores from oil-wet carbonate reservoirs, the amount of residual
gas saturation after a solvent injection was measured at water flood-out. Observations, in
percentage of pore volume, were
23.5 41.4 44.5 31.5 37.2 35.7 45.6 51.5 22.0
34.0 42.5 33.5 46.7 46.9 39.3 32.5 36.4 51.2
Calculate a 95% CI for the true average amount of residual gas saturation.
