According the World Health Organization, the Body Mass Index (BMI=Weight in Kilograms/Height in Meters) of a healthy 5-year old girl is 15. After Palmyra, Syria, got liberated from the Islamic State, the World Food Program asks you to conduct an early assessment situation of the nutritional situation in Palmyra. You measure the height and weight of a random sample of 225 five-year old girls and obtain a sample BMI average of X = 14. 5785 and a sample standard deviation 0.01 the hypothesis that the children of Palmyra are of s=2.25. Test at a = undernourished as measured by the BMI.
