Q1) 
Independent random samples of the selling prices of houses in four districts were taken. The selling 
prices (in thousands of dollars) are shown in the accompanying table. Test the null hypothesis that 
population mean selling prices are the same in all four districts.

Assumptions: 
 Independence of cases 
 the distributions of the residuals are normal 
 Equality of variances, called homoscedasticity 
 
Analysis: 
Ho: there is no significant difference in the mean selling prices across 4 districts. 
H1: at least one of the mean selling prices across 4 districts differ significantly. 
With F = .192 and p-value > 0.05, I fail to reject ho and conclude that there is no significant difference in 
the mean selling prices across 4 districts.  
Hence here there is no need to apply Post Hoc analysis.
Output: 
ANOVA: Single Factor 
      
       SUMMARY 
      Groups Count Sum Average Variance 
  District A 5 379 75.8 231.2000 
  District B 5 385 77 174.5000 
  District C 5 383 76.6 25.8000 
  District D 5 362 72.4 29.
