In the United States, males between the ages of 40 and 49 eat on average 103.1 g of fat every day with a standard deviation of 4.32 g. Assume that the amount of fat a person eats is normally distributed. Round the probabilities to four decimal places. It is possible with rounding for a probability to be 0.0000. a) State the random variable. b) Find the probability that a randomly selected male in the US between the ages of 40 and 49 has a fat consumption of 91.64 g or grams or more. c) Find the probability that a randomly selected male in the US between the ages of 40 and 49 has a fat consumption of 100.44 g or grams or less.
