Calculate an interval estimate for p, the proportion of houses larger than 1700 sqft. in the population. Use your data to calculate p-bar, and construct a 90% confidence interval for p. Show formula used, values plugged-in and final calculation.
Did not include data because I am just trying to find the proper formula to use
