Is there such a thing as Jewish American culture?

A friend of mine is Jewish and she has mentioned about being brought up in the Jewish Culture.

I asked my Jewish friend exactly what she meant by growing up in a Jewish culture, here is what she said:

Expectation of being more aggressive and assertive with others

Expectation of academic and career excellence

Stronger interest in the arts, music, cultural events than the general population

Certain social and interpersonal behaviors that are very assertive
