Business Problem
This is a peer comparison project. Suppose
that you are working for Samsunge in
customer experience management team. The idea is to regularly monitor the
customer satisfaction levels and peer company moves. The competitor company is Appleo.
The objective is to test two main hypothesis.
1.The Samsunge Average customer satisfaction score is minimum 75%.
2.The overall average satisfaction score of Samsunge is same as Appleo. There is no significant difference in the satisfaction scores
1.The Samsunge Average customer satisfaction score is minimum 75%.
2.The overall average satisfaction score of Samsunge is same as Appleo. There is no significant difference in the satisfaction scores

might be possible that both hypothesis are correct, one of them is correct or
both of them are wrong. Perform the relevant testing to verify these
assumptions
