For the given scenario, determine the type of error that was made. If any. (Hint: Begin by determining the null and alternative hypotheses)

A radio station has accepted 26 as the mean age of its listeners. One radio station executive claims that the mean age of its listeners is greater than 26. The radio station executive conducts a hypothesis test and fails to reject the full hypothesis. Assume that in reality, the mean age of its listeners is 30. Was an error made? If so, what type?
A. Yes: Type Il error
B. Yes: Type I error
C. No correct decision
