Height and weight are two measurements used to track a child’s development. The World Health Organization measures child development by comparing the weights of children who are the same height and the same gender. In 2009, weights for all 80 cm girls in the reference population had a mean µ = 10.2 kg and standard deviation σ = 0.8 kg. Weights are approximately normally distributed. X ~ N(10.2, 0.64), where the notation N(a,b) stands for a normal distribution with mean a and variance (square of the standard deviation) b. Calculate the z-scores that correspond to the 12.2 kg. Round to one decimal place.
