Unformatted text preview: hypothesis test for the difference in two population proportions? Explain. Proportion refers to the relation between elements as a whole and the whole portion. It is nothing but a fraction element. Percentage refers to the expression of a number as a fraction of 100. Ratio is the mathematical relationship between two numbers of the same kind.
