Suppose that a report indicates that 28% of Canadian homeowners have experienced difficulty in making mortgage payments. Further suppose that a organization randomly sampled 400 Canadian homeowners from 10 cities an that 95 reported such difficulty. Does this indicate that the problem is less se among homeowners in these cities? Assuming that p represents the proporti homeowners in these 10 cities that experience difficulty in making mortgage payments, the correct null and alternative hypotheses to investigate this que: H0:p=0.28 and HA:p=0.28 H0:p=0.28 and HA:p=0.28 H0:p=0.28 and HA:p>0.28..
