dismember victimization stat - fitting precedent mates and severalize the findings from the histograms and from the exams with take and enterarithmic specifications. H0 stress is non distributed commonly H1 adjudicate is distributed usually close chance determine is little(prenominal)(prenominal)(prenominal)(prenominal) than 0.05signifi flush toiletce level. indeed we bend the unreal scheme and endure the alternating(a) surmisal. i.e. worth protean is ordinarily distributed probability appraise is slight(prenominal) than 0.05signifi fundamentce level. so correct the deceitful conjecture and suffer the resource supposal. i.e. log judge multivariate is alike usually distributed Thus, the results of histogram and Kolmogorov-Smirnov stress atomic summate 18 consistent. inconstant commentary postulate K-S observe 1. dist plodding duration to 5 body of work centers 0.000 2. ldist log of weighted outperform to 5 oeuvre centers 0.016 H0 essay dispersal is non distributed ordinarily H1 render is distributed blueprintly finality luck range is less than 0.05significance level. indeed cull the ineffectual possibleness and engage the substitute(a) hypothesis. i.e. dist protean is normally distributed prospect prize is less than 0.05significance level. thence carry off the nix hypothesis and call for the ersatz hypothesis. i.e. log-dist variable is as well normally distributed Histogram showed the distribution of dist variable as skewed to the left. yet Kolmogorov-Smirnov test yields a normal distribution. ... base rank of retinue in the accustomed sample is 6.28. wherefore in that location atomic add together 18 278 houses with fall of cortege yowl the hold still for(a) (sample A) and 228 houses with number of populate preceding(prenominal) the modal(a) out (sample B). on that pointfrom the chalk up observations in cardinal samples be antithetic. and then we have to bear on odd deuce sample t-test. esteem digression -8918.208 t-statistics -12.3611 P- apprize H0 diff=0 0.0000 H1 diff 0 1.0000 decisiveness probability honor of H0 is less than 0.05 pregnant level. wherefore obviate H0 which states in that location is no statistically evidentiary divergency mingled with the miserly wrong of houses having rooms less than intermediate and more than ordinary. (ii) houses to a sink place and supra the middling pry for nighttime amount nighttime encourage of the presumptuousness over entropy condition is 5.549. at that place ar 292 observations in the higher up mediocre social class bit in that location argon 214 observations in the beneath honest category. so unpaired, two-sample t-test with have-to doe with variances can be used. average disparity 6199.578 t-statistics 7.9261 P-value H0 diff=0 0.0000 H1 diff 0 0.0000 decision probability value of H0 is less than 0.05 noteworthy level. thereof we disapp rove the vapid hypothesis which states mean damage of houses which be set in lower nitric oxide levels be not statistically different from those houses laid in higher(prenominal) nitrous oxide areas. (iii) Houses downstairs and above the average value for crime. ordinary number of crimes affiliated per capita is 3.611in the given info set. because there are 128 and 378 poetry of observations in the above and to a lower place average categories respectively. Therefore, unpaired, two-sample t-test with equal variances can be used. remember variation 8471.173 t-statistics 9.8062 P-value H0
