Each box will be test marketed in three different stores for a period of a month. Below you are given the information on sales. What conclusion do you draw at alpha = 0.05? The mean of box 3 is larger than the others therefore the null hypothesis is accepted. The mean of box 3 is larger than the others, therefore the null hypothesis is rejected. Even though the mean of box 3 is larger than the others, the null hypothesis is not rejected. Since all means are the same the null hypothesis is rejected. None of above is true.Explanation / Answer
