Two companies, A and B, make express delivery for small-item packages in a city. Company A charges a flat fee of RM70 per package regardless of weight. Company B charges RM20 plus RM3.50 per kilogram of item. The weights of small-item packages delivered in the city have a normal distribution with mean of 9 kilograms and a standard deviation of 6.2 kilograms. Find a) the probability that Company B would charge more than Company A to deliver a small-item package.
b) the mean and standard deviation of amount charged by Company B to deliver a
small-item package.
