Sample size (or number of clusters) by treatment arms

Before
There are two randomized elements in the experiment: (1) whether the good in question is hand sanitizer or face masks and (2) whether the seller price range is $10.00 - $15.00 or $30.00 - $35.00. These two elements are crossed with each other and the sample size is split evenly amongst them.

After
There are two randomized elements in the experiment: (1) whether the good in question is hand sanitizer or face masks and (2) whether the seller price range is $7.50 - $10.00 or $27.50 - $30.00. These two elements are crossed with each other and the sample size is split evenly amongst them.
