A city expressway with four lanes in each direction was studied to see whether drivers preferred to drive on the inside lanes. A total of 1000 automobiles were observed during the heavy early-morning traffic, and their respective lanes were recorded. The results are shown in the following table. Lane Count 1 294 2 276 3 238 4 192 Total 1000 To test whether there is sufficient evidence to indicate that some lanes are preferred over others, they test Ho: P₁ = P2 = P3 P4 vs. Ha : Pi ‡ Pj, for some i ‡j, i, j = 1, 2, 3, 4. What is the observed test statistic? Note: Please round your numerical answer to three decimal places.
