Three paint manufacturers were examined to see if the mean amount of paint in their 1 gallon cans differ. Five paint cans were measured from each manufacturer, and the results are recorded below. At the .05 level of significance, is there a difference in the amount of paint these three manufacturers sell? Manufacturer 1 Manufacturer 2 Manufacturer 3 .98 1.04 1.01 1.01 1.01 .98 .96 1.02 .99 1.02 1.05 1.02 1.00 1.02 .97 What is the alternative hypothesis? Ha: µ1 = µ2 = µ3 Ha: at least 1 µ is different Ha: µ1 ≠ µ2 ≠ µ3 Ha: all µ are different
