Null hypothesis(H )0 t he null hypothesis states that,the three different categories of cars have same mean highway fuel consumption. Symbolically, H 0 1 = 2 . 3 Where , = the mean highway fuel consumption of cars having 4 cylinders. 1 = the mean highway fuel consumption of cars having 6 cylinders. 2 3 the mean highway fuel consumption of cars having 8 cylinders.
