An experienced census official feels that she can accurately estimate the number of inhabitants of a city block by simply noting the size of the block and the types of buildings (Single family homes, apartments, businesses, etc.) that are found on the block. This procedure, if accurate, would be much quicker and cheaper than visiting each residence and taking a survey of its inhabitants. The data below are estimates of block populations provided by the official for 10 blocks in a large city, and the actual numbers of inhabitants for the same 10 blocks 189 Inhabitants of City Blocks 115 83 213 184 113 214 180100 82 120112137 85 Estimate 229 Actual 89 161 79 203 128 Copy Data Step 2 of 2: Is there evidence of a linear relationship between the actual number of inhabitants and the estimated number Test at the 10 level Answer 2 Points < m Tables Keypad Keyboard Shortcuts Prev N.
