I'm stuck on the following question and think my answer is incorrect
'An optician noticed the following information about colour-blindness in males and females. Is there a significant difference between the observed frequency of colour blindness in males and females?'
Colour blind males - 56
Not colour blind males - 754
Colour blind females- 14
Not colour blind females- 536
