Hypotheses Testing for Likert Scale data

#1
Hi

In my study I have hypothesized the following:

Top Management Support is a critical success factor on I.T. projects.
Adequate Resourcing is a critical success factor on I.T. projects.
Having a skilled team is a critical success factor on I.T. projects.
Next I have asked these questions in my survey to test the above hypotheses (via Likert Scale): - Top Management Support is a critical success factor on I.T. projects. Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree - Adequate Resourcing is a critical success factor on I.T. projects. Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree - Having a skilled team is a critical success factor on I.T. projects. Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree

What is the best way to accept or reject my hypotheses from the data I have gathered?

I will be entering the data into SPSS, Strongly Agree = 5, Agree = 4 etc.

Thanks in advance. Martin
