BUAD 310 HW1 Problem 1 a, f, g, h, j, m, o, r, t, w 1A.) Explain the Population, Parameter, Sample and Statistics. Population is the total collection of elements of interest in a given study. Parameter is a number that provides a quantitative description of some characteristic of a population . Sample is a subset of a population. Statistic is a numerical quantity that provides information concerning some characteristic of a sample . 1F.) Calculate the Measures of Center. Mean: (361+393+430+543+566+610+763+851+886+886+887+976+1039+1124+1267+1328+1 415+1425+1444+1450+1476+1542+1544+2048+2197+3000+3050+3120+4000+4300)/3 0 = 1497.37 Median: 1267+1328/2 = 1297.5 Mode: 886 1G.) Calculate the Measures of Variability. Range: 4300-361 = 3939 Variance: [ (361-1297.5)^2 + (393-1297.5)^2+(430-1297.5)^2+(543-1297.5)^ 1297.5+ (566-1297.5)^2 + (610-1297.5)^2+(763-1297.5)^2+(851-1297.5)^ 1297.5+ (886- 1297.5)^2 + (886-1297.5)^2+(887-1297.5)^2+(976-1297.5)^ 1297.5+ (1039-1297.5)^2 + (1124- 1297.5)^2+(1267-1297.5)^2+(1328-1297.5)^ 1297.5+ (1415-1297.5)^2 + (1425- 1297.5)^2+(1444-1297.5)^2+(1450-1297.5)^ 1297.5 + (1476-1297.5)^2 + (1542- 1297.5)^2+(1544-1297.5)^2+(2048-1297.5)^ 1297.5 + (2197-1297.5)^2 + (3000-
