The Food and Nutrition Research Institute (FNRI) of the Department of Science and Technology (DOST) recommends that children 1 to 3 years old have a 1070 kilocalories (kcal) of energy intake. A random sample of 78 children 1 to 3 years old from a certain region reported an average energy intake of only 440 kcal with a standard deviation of 190 kcal. Can you conclude that the mean energy intake of children 1 to 3 years old from this region is significantly lower than the FNRI recommendation of 1070 kcal? Use a 5% level of significance.
