Weights in kilograms of boys at the start of 1st grade are approximately normal with mean 25, standard deviation 5. Use the 68-95-99.7 Rule to estimate the following weights. (Round your answers to the nearest kilogram.) (a) The probability is 0.002 that a boy at the start of 1st grade is less than what weight? Correct: (smaller value) (larger value) (b) The probability is 0.12 that a boy at the start of 1st grade is more than what weight? kg (smaller value) kg (larger value)
