Nasa scientists obtained the following data from airborne radiometer scans using the estar method of aperature synthesis soil moisture percentages: 19,16,15,16.5,15,14 source: d. m. levine, a. j. griffis, c. t. swift, and t. j. jackson, "estar: a synthetic aperature microwave radiometer for remote sensing applications," proceedings of the ieee, december 1994, p. 1795 these data represent sample measurements taken over the 220-240 degree k brightness temperature range. the theoretical model states that the mean volumetric soil moisture percentage should be 13.5%. use the confidence interval approach to conclude whether the sample data support or refute the null hypothesis that the mean estar measurements equal the theoretical level, using a .05 level of significance. lower 95% confidence limit upper 95% confidence limit . what is your conclusion?
