Psychology and Human Behavior

Historically, the three most popular home-improvement projects are interior decorating, landscaping, and expansion (respectively). A random sample of homeowners and condominium owners was obtained asked whether they planned any landscaping within the next year. The data are given in the following table.

Residence	Sample size	Number who are planning to landscape
Homeowner	261	90
Condominium owner	303	65

Is there any evidence to suggest that the proportion of homeowners planning a landscaping project is more than 0.10 greater than the proportion of condominium owners planning a landscaping project? Use a = 0.01.
