7)- An American Housing Survey conducted by the U.S. Department of Commerce revealed that 705 of 1,500 sampled homeowners are do-it-yourselfers. They did most of the work themselves on at least one of their home improvements or repairs (Bureau of the Census, Statistical Brief, May 1992). Estimate the true population proportion of American homeowners who do most of the home improvement or repair work themselves using a 95% confidence interval. Interpret the result.
