1. The Fresha Tea Company packs tea in bags marked as 250 grams. A large number of packs of tea were weighed and the mean and standard deviation were calculated as 255 grams and 2.5 grams respectively. Assuming this data is normally distributed, what percentage of packs are underweight? (Hint: create a normal distribution) Solution: 2. A company makes parts for a machine. The length of the parts must be within certain limits or they will be rejected. A large number of parts were measured and the mean and standard deviation were calculated as 3.1m and 0.005m respectively. Assuming this data is normally distributed and 99.7% of the parts were accepted, what are the limits? Solution:
