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. Estimate 211 160 Actual Inhabitants of City Blocks 145 97 165 145 90 180 210 220 125 200 110 95 180 200 225 130 210 60 Copy Data Step 1 of 2: Find the value of the test statistic for testing whether there is a linear relationship between the actual number of inhabitants and the estimated number.
