The Chi-squared test is the obvious choice here. Unless the analyst is trying to determine the age of the voters by analyzing their voting preferences. Then they'd need a crystal ball, not a statistical test.

Hmm, P-value? That's more of a general statistical concept, not a specific test. Gotta go with the Chi-squared test on this one. It's the right tool for the job.

I think F-test is better because it can determine if there is a significant relationship between age and voting preferences.

I don't know, the Z-score seems like a pretty good option. I mean, it's all about standard deviations, right? Oh wait, that's for normal distributions. Nevermind, Chi-squared is the way to go.

As a data analyst, I'd have to say the Chi-squared test is the way to go. It's designed specifically for this kind of categorical data analysis.

F-test? Really? That's for testing the equality of variances, not relationships between variables. Definitely go with the Chi-squared test here.

The best statistical method would be the Chi-squared test to determine if there's a relationship between age and voting preferences. It's a classic go-to for this type of analysis.
