PROBLEM 1(35pts) You are charged with conducting an investigation in relation to herbicide pollution of IA lakes. Let X denote the act of measuring the level of a certain chemical in any randomly chosen lake. Assume X N(Hr,ax), and that the lakes to be chosen for testing are such that the data collection variables {X^)% can be assumed mutually independent. Let(ux x ) denote the usual estimators of (Ax O,) Data collected on n-50 lakes resulted in (Ax-323. Ở,-69) (a)(12pts)...
