The formula for the standard error for a proportion is:      E=√p⋅(1−p)/n If 1.5% of apartments are vacant and you sample 721 apartments, then the standard error is:      E=√0.015⋅(1−0.015)/721  Calculate this number rounded to five decimal places.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
