I am posting this second time so plz solve this correct ly plz
Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. Cloud seeding has been studied for many decades as a weather modification procedure (for an interesting study of this subject, see the article in Technometrics, "A Bayesian Analysis of a Multiplicative Treatment Effect in Weather Modification", Vol. 17, pp. 161-166). The rainfall in acre- feet from 20 clouds that were selected at random and seeded with silver nitrate follows: 19.0, 31.7, 20.8, 28.1, 23.3, 19.8, 32.8, 24.4, 22.2, 28.9, 32.9, 28.1, 26.0, 25.7, 27.9, 22.8, 30.2, 35.8, 27.7, 32.6 (a) Can you support a claim that mean rainfall from seeded clouds exceeds 26.0 acre-feet? Use a = 0.01. There is insufficient vevidence to indicate that the true mean rainfall is greater than 26.0 acre-feet at a = 0.01. (b) Compute the power of the test if the true mean rainfall is 28.0 acre-feet.

Use a = 0.01. There is insufficient evidence to indicate that the true mean rainfall is greater than 26.0 acre-feet at a = 0.01. (b) Compute the power of the test if the true mean rainfall is 28.0 acre-feet. i 0.0 Round your answer to one decimal place (e.g. 98.7). (c) What sample size would be required to detect a true mean rainfall of 28.5 acre-feet if we wanted the power of the test to be at least 0.9? nz i 75 Round your answer to the nearest integer.
