a) Sales in a week has a Normal distribution with mean 6,767 and standard deviation 389. We want to create 12 intervals for sales, such that each interval has the same probability (of 1/12 = 0.08333). The intervals are "below a1", "between a1 and a2", ..., "between a10 and a11", and "above a11". What should be the value of a11? (Provide one decimal place)
