Seven individuals were from Neighbourhood A and seven were from Neighbourhood B. The data were entered into SPSS and an independent samples t-test was performed to test the following hypotheses, with a = 0.05. HO: The mean number of mass transit trips is equal for both neighbourhoods; µA = µB H1: Use of the mass transit system varies between people from Neighborhood A and Neighbourhood B: µA # µB From the SPSS output above, you may assume that the variance of the sample from Neighorhood A is equal to the variance of the sample from Neighborhood B. True False
