The frequency distribution below represents the square footage of a random sample of 500 houses that are owner occupied year round. Approximate the mean and standard deviation square footage. $$\begin{array}{lc}\text { Square Footage } & \text { Frequency } \\\hline 0-499 & 5 \\\hline 500-999 & 17 \\\hline 1000-1499 & 36 \\\hline 1500-1999 & 121 \\\hline 2000-2499 & 119 \\\hline 2500-2999 & 81 \\\hline 3000-3499 & 47 \\\hline 3500-3999 & 45 \\\hline 4000-4499 & 22 \\\hline 4500-4999 & 7 \\\hline \text { Source: Based on data from the U.S. Census Bureau }\end{array}$$
