Assume a member is selected at random from the population represented by the graph. Find the probability that the member selected at random is from the shaded region of the graph. Assume the variable x is normally distributed. Pregnancy Length in a Population of New Mothers 280 <x<292 Q μ=271 G=11 241 280 292 Pregnancy length (in days) The probability that the member selected at random is from the shaded area of the graph (Round to four decimal places as needed.)
