Suppose that the time spent by children under the age of 12 in front of a screen per year has the distribution N (1500,250); i.e, is Normal with mean =1500 and standard deviation \sigma σ=250. What proportion of children spend between 1250 and 1750 hours in front of a screen? (Express your answer as a decimal, not a percentage.)
