According to the World Health Organization, the average height of a one-year-old child is 29". You believe children with particular disease are smaller than average, so you draw a sample of 20 children with this disease and find a mean heigh 27.5" and a sample standard deviation of 1.5". The test statistic is -4.4721 and the p-value is 0.00013 using the calculator function TTEST. If a=0.05, what conclusions can be made? Provide a detailed conclusion including contextualization to the given scenario.
