By using the statistics table for the pHQ1994 for the selected sample houses it shows that the mean is -3.23. The standard deviation is 25.586 and the range is 142. For the whole neighbourhood in 1994 the mean is 1.52, the standard deviation is 27.261 and the range is 186. The selected sample houses in Aylmer Avenue standard deviation is 25.6% where the whole Glengarry neighbourhood standard deviation is 27%, there is a similar average variability with around a 2% difference. Aylmer Avenue range is more narrow than Glengarry. The best house on Aylmer Avenue is 24% which is under the best house in Glengarry 94. 49 houses in Aylmer represents -6% (1/20) of Glengarry 781 houses. To finish the distance from the core hypothesis predicts that houses closer to the core of downtown will be in a worst condition. Therefore the distance from the core hypothesis predicts that houses will be more poorly maintained than the rest of Glengarry 94 Lower pHQ due to Aylmer Avenue begin near the core as it is downtown. A two—tailed reach hypothesis states Aylmer pHQ has significantly higher/lower than Glengarry, so the null hypothesis states no difference between the sample and the population.…show more content… The Zobs is 1.21, neither below -1.96 or above 1.96 Zcrittial at 5% (.05) alpha. Therefore it fails to reject the null hypothesis, so there is going to be no difference between the sample and the population of 1994. The houses on Aylmer Avenue had similar pHQ, it does not support hypothesis for better/worse Aylmer Avenue houses near
