I am currently doing my maths studies IA and I have written down my hypothesis (I have 5) but I have some questions.

 

How many hypothesis do I need to test? 

 

Let me give you an example so maybe someone can help me with that.

 

 

1.    AGE & MUSIC

H0 null hypothesis: The person’s age is independent of their knowledge about music.

H1 alternative hypothesis: The person’s age is dependent of their knowledge about music.

 

^^^ that is my first hypothesis. 

I have 4 columns of raw data.

 

Age|Gender|Music|Film 

 

(Music is out of 10 and film out of 11 - i did a questionnaire and the music and film columns are how many each person had correct).

 

How do I find the average for each hypothesis?

 

I really need help on this. ASAP. I would be very grateful!
