Statistics Question?!?!?

An analyst asked 40 people a question with a Likert scale answer choices, coded as follows:
◦1: Strongly Disagree
◦2: Disagree
◦3: Neither Agree nor Disagree
◦4: Agree
◦5: Strongly Agree

She reported that the average response was a 2.5. What can we conclude from this?



a. Overall, the people surveyed slightly disagree with the question

b. Nothing, the response scale is categorical and should not be translated into a linear coding system

c. Nothing, we do not know the distribution of responses

d. Overall, the people surveyed slightly agree with the question
