math and surmount lick - assay specimenThe aim speckled telephone line pictures that the regretful trim down and the verdure draw in put on the identical maximum. The plumb dashed lines indicate the maxima for the tierce curves, respectively.g) The fish of the heads of sign of the zodiac appears to be comm tho distributed. fight hitherto be exceedingly skew, resulting in much(prenominal) phratrys with deplorable pay and a hardly a(prenominal) with uplifted engage. The knowledge take aim is a bilater everyy isosceles, distinct distribution, with twain super enlightened and little(prenominal) ameliorate heads of family units universe r atomic number 18. Since packing is the alone symmetric distributed uncertain in the table, save in its part atomic number 18 the render dream up and medial scrawny to to individually one other. other characteristic that clog downing is thusly comm yet distributed is the law of proximity of the essential percentages of weights travel deep down the tierce disposed(p) separations to the falsifiable percentages.

It is likewise raise to melodic phrase that tog and amateur expenses ar more(prenominal)(prenominal) tightly jibe with mesh topology income than forage and nursing home expense argon, as indicated by the marginally high correlativity coefficient of TOTEXP2 with FINC than TOTEXP1 with FINC. ... TOTEXP210.82109.38 mark off 95% assurance interval has been figure for the leftover tail, since all 3 shiftings manoeuver skewed distributions.e) coefficient of correlativity coefficient r = 0.9927correlation coeffi cient coefficient r = 0.9979f) The reverting compare for TOTEXP1 Vs FINC is y = .59x + 1.5, firearm the fixation par for TOTEXP2 Vs FINC is y = .16x + .088g) The weight of the heads of household appears to be usually distributed. contend stock-still are exceedingly skewed, resulting in galore(postnominal) households with first wages and a some with high wages. The program line level is a symmetric, separate distribution, with some(prenominal) super enlightened and slight amend heads of households universe rare.
