Aspirin is packed in 120 tab bottles with weight normally distributed with mean 600g and standard deviation 6g. We want to figure out what is the probabilty that a bottle of aspirin randomly picked from the production batch will weigh from 598g to 602g. 1. Do we have to calculate one z-score or two z-scores? 2. The negative z-score is 3. The positive z-score is 4.The probability that a bottle of aspirin will have weight between 598g and 602g is
4. Suppose that the weight of an newborn fawn is Uniformly distributed between 2.3 and 3.9 kg. Suppose that a newborn fawn is randomly selected. Round answers to 4 decimal places when possible.
