The partner bank called the 581 customers owning a "gold card" to offer them the "platinum card" as a higher-end card. However, the partner bank decided to cancel the marketing phone calls to the 865 customers owning a "platinum card."
The partner bank was able to reach 203 out of the 581 customers. However, based on the records of the calls, we found out later that the callers failed to follow our protocol for the experiment in 36 out of these 203 calls, yielding a final sample size of 167 customers.
