Hi, I would really appreciate the help. I study research methods for psychology and reading about different tests for my exam in two weeks. I'm not sure if I've understood the Chi square test completely. Output file is attached.

The data is transport methods. Since the p-value is .000 (below .05), the result is statistically significant and we reject the nullhypothesis, am I right here? But what does that mean, what is the nullhypothesis here exactly? Does the result mean that the data does not fit with the expected distribution, or did it fit?

The reason I'm confused is that I've been reading about different tests, and nullhypothesis of the other tests is usually that it is NOT significant difference between groups or variables. And in Chi square the nullhypothesis is suddenly that it DOES fit with expected distribution? Is this correct or have I misunderstood something?

Appreciate all the help I can get
