A mean difference of zero indicates that the peppers are well distributed between the groups
Step-by-step explanation:
The mean difference between two groups is a measurement of the absolute difference between the values of the mean of each of the two groups within the experimental trial, in order to determine if an intervention changes the average of one of the groups, compared to the other which is the control group
A mean difference of zero shows that the distribution of the sizes within each group is the same, and that the pepper sizes are on average, equal in each group
Therefore, a mean difference of zero indicates that the peppers are well distributed between the groups
