g 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 1010 blocks in a large city, and the actual numbers of inhabitants for the same 1010 blocks. Inhabitants of City Blocks Estimate 119119 134134 201201 9696 139139 7474 229229 154154 221221 194194 Actual 216216 112112 205205 9292 153153 121121 145145 8585 113113 108108 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.
