The normal curve below shows the distribution of units of a product sold over 320 days. The mean is 68 units and the standard deviation is 6 units. Use the empirical rule (68-95-99.7 rule) to answer the following questions. 1. Approximately what percent of daily units sold are (Do not round percent values) a) between 50 and 86 units? b) below 62 units? % c) above 96 units? % 2. On approximately how many days are units sold (Round to the nearest whole number. Total days =320 ) a) above 68 units? b) below 96 units? c) below 56 or above 80 units? 3. Identify the interval containing the 94th percentile in the normal curve above. Select the two consecutive values containing the interval from those listed. Place the smaller of the two in the first box and the larger in the second box. The 94 th percentile units sold falls between and
