Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at their downtown Denton location to rate this new flavor. The rating is on a scale of 1 to 5, with 1 being 'not interested' and 5 being 'strongly interested'. Meth Barie's will approve the new flavor if the true mean rating is over 4.0. What is the Null hypothesis for testing whether the new ice cream should be approved?
