That's not right, you're just measuring the relationship between the mean score of all those questions. I don't think that is what the TS is asking

The correct answer is that you cannot test a multivariate factor with a t test unless there is valid reason that all the 5 questions are simply different samples of the same variable. Them you take the sample mean and test it.

If it's 5 questions testing slightly different things, you need to use multiple factor analysis to find the underlying variable that is affecting the dependent variable.
