Tukey HSD confidence intervals (with a familywise error rate of 0.05) were calculated for the mean housing prices in three neighbourhoods: A, B, and C.
Tukey HSD confidence intervals (with a familywise error rate of 0.05) were calculated for the mean housing prices in three neighbourhoods: A, B, and C. The sample means and intervals are shown. Arrange the towns from smallest sample mean on the left to largest on the right, underlining pairs for which the sample means are not significantly different. (The sample mean was largest for C and smallest for A.) Assume that conditions for ANOVA are met. Then write a sentence or two interpreting your results.

Neighbourhood A Neighbourhood B Neighbourhood C Interpret these results. O A. The mean housing price in Neighbourhood C is higher than in both Neighbourhood A and Neighbourhood B. Those two do not show a significant difference. O B. The mean housing price is higher in Neighbourhood C than in Neighbourhood A. The price in Neighbourhood B is not significantly different from either of the others. O C. The mean housing prices are all different. From largest to smallest, the order is Neighbourhood C, Neighbourhood B, Neighbourhood A. O D. The mean housing prices in Neighbourhood B and Neighbourhood C are not different, but they are both higher than the mean price in Neighbourhood A.Tukey 95% simultaneous confidence intervals A subtracted from: Lower Center B 47.76 35.18 C 50.65 108.88 B subtracted from Lower Center C 21.85 73.51
