QUESTION 5 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: 18.5, 31.2, 20.3, 27.6, 22.8, 19.3, 32.3, 23.9, 21.7, 28.4, 32.4, 27.6, 25.5, 25.2, 27.4, 22.3, 29.7, 35.3, 27.2, 32.1 (a) Can you support a claim that mean rainfall from seeded clouds exceeds 25.5 acre-feet? Use alpha=0.01 There is evidence to indicate that the true mean rainfall is greater than 25.5 acre-feet. QUESTION 6 A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wished to test Upper HO. mu>= 175 against H1: mu> 175 millimeters, using the results of n 4 samples. If the sample mean is equal to 187 millimeters, find the P-value Round your answer to four decimal places
