Cloud seeding has been studied for many decades as a weather modification procedure. The rainfall in acre-feet from 20 clouds that were selected at random and seeded with silver nitrate follows: 18.0, 30.7, 19.8, 27.1, 22.3, 18.8, 31.8, 23.4, 21.2, 27.9, 31.9, 27.1, 25.0, 24.7, 26.9, 21.8, 29.2, 34.8, 26.7, 31.6. Can we support the claim that mean rainfall from seeded clouds exceeds 25 acre-feet? Use a = 0.01 a. Test on Mean, Variance Known b. Test on Population Proportion Test on Variance and Standard Deviation d. Test on Mean, Variance Unknown
