The headline in an independent paper that services a large metropolitan area stated that 36 % ( p = 0.36) of houses cost less than $375,000. Sayed read the headline and decided to compute a confidence interval for the proportion of all houses in that area that cost less than $375,000. His 99 % confidence interval was based on a simple random sample of 100 houses from the area, and the limits of the interval where from 0.29 to 0.43 .
