Answer:0.066Step-by-step explanation:We solve this question using z score formulaz = (x-μ)/σ, where x is the raw score μ is the population meanσ is the population standard deviationFor the question mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg.x = 2.5Hence:z = 2.5 - 3.27/0.51z = -1.5098Probability value from Z-Table:P(x ≤ 2.5) =P(x < 2.5) = P(x = 2.5) = =0.065547Therefore, the proportion of baby boys that are born with a low birth weight is 0.066
