The weight of Icelandic men aged 25 to 35 follows a normal distribution with an average of 85.6 kg and a standard deviation of 9.1 kg. a) If an Icelandic man between the ages of 25 and 35 is chosen at random, what is the probability that he weighs more than 100 kg? b) If an Icelandic man between the ages of 25 and 35 is chosen at random, what is the probability that he weighs less than 75 kg? c) If an Icelandic man between the ages of 25 and 35 is chosen at random, what is the probability that he is between 75 and 100 kg? d) If an Icelandic man between the ages of 25 and 35 is chosen at random, what is the probability that he is exactly 85.6 kg? e) Sigga, a geography student, thinks the beer is good and he has a bit of a passion for it. His doctor is a little worried about Sigg's body and advises him to lose weight. Siggi therefore decides to lose weight and sets the goal of gaining that weight so that at least 30% of Icelandic men between the ages of 25 and 35 are heavier than him. What weight does Siggi need to reach?
