If the Voice of the Customer solution is accidentally deleted or misconfigured, it might not be able to receive survey responses.
The null hypothesis is created from the hypothesis by adding the words "no" or "not" to the statement.
For example, the null hypotheses for the two examples would be: There is no significant relationship between a customer's age and their level of satisfaction with the service.
