The weight, in kilograms, of cereal in a box can be modelled by a normal distribution with Mean u and standard deviation 5.4 kg. Given that 10% of boxes contains less than D kg. Find. a. The value of u. b. The percentage of boxes that contain more than (D+4) kg. c. If the machine settings are adjusted so that the weight of cereal in a box is normally distributed with mean (D+3) kg and standard deviation of o. Given that the probability of boxes contains between D kg and (D+6) kg is 0.9671, find the value of o.
