a. 6.922 b. 0.269
c". 0.179
d. 3.218
e. 1852.61 , with a 2 bedroom home or larger
(population 2). You simply ask them ‘Would (population 1) and those with a 1 bedroom home or smaller you be willing to pay $1,000 for your current access to the rail line?” noting the appropriate responses. 160
of the 200 replied ‘yes’ in population 1 and 65 of the 100 in population 2. In a discussion with your urban
economics professor, you become interested in an alternative hypothesis of H1 : p1 — p2 > .05 as this may
relate well to the actual proximity these households choose in buying a home. What is the value of the test statistic for this hypothesis?
