The first analysis was conducted in order to determine if there is a dissimilarity of capitalization rate between CASBEE certified buildings (green buildings) and non-certified buildings (conventional buildings). Table 2 represents basic statistical information such as sample size, mean, standard deviations, and standard error mean for both the dataset.
The test statistic of the test of the difference between two population means depends on whether or not this hypothesis is rejected. Since this output, the result shows that p-value 0.052 > significance level 0.05, this hypothesis cannot be rejected. Therefore, we can conclude that the populations have equal variances.
“Hypothesis Ho: the population means of the two groups are equal”.   ...Download file to see next pagesRead More
