A nutritionist conducted a study on the eating patterns of early adolescent boys and girls. Calorie intake is normally distributed for both boys and girls. The population means are 3300 calories per day for boys and 2900 calories per day for girls. The population standard deviations are 790 for boys and 720 for girls. The nutritionist believes that children may have an eating disorder if they are in the bottom 2% the distribution. Based on this, if a child’s intake is1600 calories per day, should the nutritionist be concerned that this child may have an eating disorder? (Compute for each gender separately). Does it make a difference if this child is a boy or a girl? Explain your answer.  What proportion of girls consume between 2000 and 2400 calories per day?        Is the proportion of boys who consume between 2000 and 2400 calories per day the same, higher, or lower than the proportion of girls who consume between 2000 and 2400 calories per day? Explain your answer.
