Use the sample data to construct the following statements filling in the blanks with the answers you calculate A. Use the sample data to construct a 95% confidence interval for the mean price of a home in Winston-Salem. Since CL = 95%, a = 0.05. Determine the t-score associated with this CL and use it to determine the error bound of the population mean (EBM). Finally, construct a statement in the context of the problem that explains your result. (Use the following statement as a template and fill in the blanks with your results.) "We believe, at the _% confidence level, that the true population mean of home prices in Winston-Salem lies between $. and $ B. Use the "plus four" method to estimate the 95% confidence interval for the population proportion of single-floor homes in the area. Remember, you must calculate p', q', 20.025 in order to determine your error bound of the population proportion (EBP). Write a sentence that interprets the estimate in the context of the situation in the problem. Include the confidence level and confidence interval.

Use the sample data to construct the following statements filling in the blanks with the answers you
calculate
A. Use the sample data to construct a 95% confidence interval for the mean price of a home in
Winston-Salem. Since CL = 95%, a = 0.05. Determine the t-score associated with this CL
and use it to determine the error bound of the population mean (EBM). Finally, construct a
statement in the context of the problem that explains your result. (Use the following statement
as a template and fill in the blanks with your results.)
"We believe, at the
Winston-Salem lies between $
% confidence level, that the true population mean of home prices in
and $
B. Use the "plus four" method to estimate the 95% confidence interval for the population
proportion of single-floor homes in the area. Remember, you must calculate p', q',
and 20.025 in order to determine your error bound of the population proportion (EBP). Write
a sentence that interprets the estimate in the context of the situation in the problem. Include the
confidence level and confidence interval. (Use the statement below as a template.)
"We believe, at the_% confidence level, that the true population proportion of single-floor
% and
homes in Winston-Salem lies between
%."
