Height and weight are two measurements used to track a child's development. An organization measures child development by comparing the weights of children who are the same height and the same gender. In a certain year, weights for all 80 cm girls in the reference population had a mean y = 11.4 kg and standard deviation = 0.8 kg. Weights are normally distributed. XN(11.4, 0.8). Calculate the z-scores that correspond to the following weights and interpret them. (Round your numerical answers two decimal places.) (a) 12.2 kg Z= A
