1) In the US, about half of all homes with a basement also have a sump pump. A plumbing company surveys 673 homeowners with basements, chosen through a random sample, and finds that of those 673, there are 392 who own a sump pump. Does this survey constitute significant evidence that Chicago homes with basements have sump pumps at a higher rate than the average in the US? Use a hypothesis test to support your findings.
