6) The distribution of weights of ants in a colony can be modeled by a normal distribution with mean 1 = 5 milligrams and standard deviation o = 1.2 milligrams. Let X = the weight (in milligrams) of a randomly selected ant in the colony. (a) Label the mean and the points that are 1, 2, and 3 standard deviations from the mean. (7 points) Use the 68-95-99.7 rule to approximate: (b) Find P(X > 7.4), Show all work. (3 points) (c) The probability that the ant has a weight between 2.6 and 6.2 milligrams? Show all work (3 points)
