Explanation Given: 44% of female undergraduate and 39% of male graduate take on debt. Formula used: The expression of mean is written as, μ = n p Here, μ is the mean. The expression of standard deviation is written as, σ = n p ( 1 − p ) Here, σ is the standard deviation. Expression for standard normal variable is written as z = x − μ σ Calculation: Use the formula of mean and substitute 75 for n and 0.39 for p . μ = ( 75 ) ( 0.39 ) = 29.25 Use the formula of standard deviation and substitute 75 for n and 0.39 for p . σ = ( 75 ) ( 0.39 ) ( 1 − 0.39 ) = ( 75 ) ( 0.39 ) ( 0.61 ) = 17
