Which significance test should I use?

#1
I have a research questionnaire using a five point Likert scale (not at all, little, neutral, considerable, significant).
I want to statistically analyse the results of each question to figure out the significance of each question answers.
For example:
Which of the following best describes the efficiency of using Earned Value Management in estimating*the project end date?
(not at all, little, neutral, considerable, significant).

Kindly specify the testing steps in brief.

Thanks in advance.
