Problem 11-18 (modified). nasa scientists obtained the followingdata from airborne radiometer scans using the estar method ofaperature synthesis. soil moisture percentages: 19,16,15,16.5,15,14source: d. m. levine, a. j. griffis, c. t. swift, and t. j. jackson, "estar: a synthetic aperature microwave radiometer forremote sensing applications," proceedings of the ieee, december 1994, p. 1795.these data represent sample measurements taken over the 220-240degree k brightness temperature range. the theoretical model statesthat the mean volumetric soil moisture percentage should be 13.5%.use the confidence interval approach to conclude whether the sampledata support or refute the null hypothesis that the mean estarmeasurements equal the theoretical level, using a .05 level ofsignificance. lower 95% confidence limit = 1.upper 95% confidence limit = 2.
