Thank you for answering my question, but I am still a little confused because the alpha value is greater I understand that we have to reject. My next question is how do I answer the question in words for the investion?

imagine you work in the HR department of a large company. Your supervisor is interested in the mean annual performance review scores for all the employees in the sales department. The performance review scores range from 1 to 5, with 5 being exceptional and 1 being unacceptable. They have been asked by the CEO to examine the performance review scores to determine if the mean is above 3.5, because limited funds are available for raises. Your supervisor wants to determine if this is correct and has asked you to investigate.

You randomly sample 30 annual performance reviews and record the scores.
