H1: There is a significant relationship between commuting and gender.

SPSS results showed that generally, respondents went to work by driving a car. Directionally, females are more likely to take the passenger train (73%), while more than the majority of male respondents work at home (62%). However, these findings are not significant, and the X2 asymp. sig value of 0.101 showed that p< 0.05, which means that Ho is retained -- that is, there is no significant relationship between commuting and gender.

To determine the significance of the relationship between the variables savings and loans and other financiers, an independent samples t-test will be conducted as the statistical analysis. The null hypothesis for this analysis is:

Ho: There is no significant difference between savings and loans and other financiers in the average payback period necessary to justify solar heating systems for residences.

To conduct the t-test, the following formula will be used:

observed difference between sample means / standard error of the difference between means

X1-X2 / S (x1-x2) where: S (x1-x2) = ?sx12 + sx22

Applying the given data to the formula above, we get:

Savings & Loans

Other Financiers

Sample mean

Standard error

S (x1-x2)

beer and soda both for non-directional (two-tailed) and directional (one-tailed) tests, as reflected in the p values of the variables, wherein p>.05 -- 0.06 and 0.13, respectively.
