ev 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.

Test at the 0.10 level. Answer 2 Points Keypad Keyboard Shortcuts N We fail to reject the null hypothesis. There is, at the 0.10 level of significance, sufficient evidence of a linear relationship between the actual number of inhabitants and the estimated number. We reject the null hypothesis. There is not, at the 0.10 level of significance, sufficient evidence of a linear relationship between the actual number of inhabitants and the estimated number. We fail to reject the null hypothesis. There is not, at the 0.10 level of significance, sufficient evidence of a linear relationship between the actual number of inhabitants and the estimated number. We reject the null hypothesis.
