Public Policy and Political Science
A local planning board must consider whether to require all new projects with five or more apartments to designate some of the units as rentcontrolled. A random sample of 100 apartments in Cheyenne, Wyoming, was obtained, and 9 were found to be rent-controlled.
Is there any evidence to suggest the proportion of rent-controlled apartments is less than 10%? Let a = 0.05, and use the p value associated with this hypothesis test to draw a conclusion.
