In filling bags of nitrogen fertilizer, it is desired to hold the average overfill to as low a value as possible. The lower specification limit is 22.00 kg (48.50 lb), the populations mean weight of the bags is 22.73 kg (50.11 lb), and the population standard deviation is 0.80 kg (1.76 lb). What percentage of the bags contains less than 22 kg? If it is permissible for 5% of the bags to be below 22 kg, what would be the average weight? Assume a normal distribution. [If the last digit of your 800 numbers is EVEN number; for example: 800xxxxx2]
