Click here to see page 1 of the table for areas under the standard normal curve. Click here to see page 2 of the table for areas under the standard normal curve. .... (a) The percent of items that lie within 1.15 standard deviations of the mean in any distribution is at least %. (Round to the nearest tenth as needed.) (b) The percent of items that lie within 1.15 standard deviations of the mean in a normal distribution is %. (Round to the nearest tenth as needed.)
