Annual income is considered a ratio scale, which is a type of quantitative measurement that includes an absolute zero point and allows for meaningful comparisons. It is not nominal, as nominal data are categorical and do not have a meaningful order. While it has some interval characteristics (such as the ability to calculate differences), the presence of a true zero (zero income) makes it more accurately classified as ratio.

No. The interval level is more refined and so enables calculations which are not available at the nominal level.
A group, as a single entity, would be nominal.
Occupation is nominal data. There is not an order to the category occupation, so that eliminates ordinal and interval.
