I use to find that students respoded well to the idea that the hypothesis
test told you, within the limits of likelihood set, where the parameter
wasn't while confidence intervals told you where the parameter was.

chance events.

In general, as these things always seem to go, many folks call any item from
a summated rating scale a Likert item. But, like the use of relationship
instead of relation, it seems to be a difficult practice to stamp out.

samples are small, the tests have no power to detect violations. There is no substitute for examining your data. If the data are badly skewed, you don't need a normality test to tell you that, a simple histogram will do it.
