1. The content of a medium jar of jocoque follows a normal distribution with a mean of 500 grams and a standard deviation of 43 grams. d) What must be the standard deviation so that only 4% have a content greater than 550 grams? e) Calculate the probability that a batch of 60 jars at most 10 have a content greater than 575 grams f) If jars are selected one at a time, calculate the probability that at least 15 jars are checked to find 4 that have a content greater than 575 grams. g) If a sample of 20 jars is taken, find the probability that the total content of the jars is less than 17.1 kilos.
