Suppose that a quantitative character is normally distributed with mean u = 13.1 and standard deviation o = 3.2. Find an interval centered at the mean such that 95% of the population falls into the interval. Do the same for 99% of the population. The interval for 95% of the population is (Round to one decimal place as needed.)
