1. A wildlife biologist collected beaver from trappers from a population in Mississippi (Population #1) to assess the average weight in this region of the Southeast. She recorded weights in 5.0 lb. increments What is the population mean weight (M) and SD (a) for this beaver population? (15 points) u= {xP(X = x) o? = X(; - u)*P(_X = x) o=VO? X-H (x - 1)(x-u)? P(X=x) Weight (x) Count P(X=x) *.P(X=x) 15 4 0.0090 20 12 0.0271 25 48 0.1086 30 46 0.1041 35 73 0.1652 40 112 0.2534 45 61 0.1380 50 55 0.1244 55 21 0.0475 60 10 0.0226 442 1.0000 Hint: You should get # = 38.8 and 0 = 9.5
