The Courier Guy, a package delivery service, divides their packages into weight classes. Suppose that packages in the 14-to-20-kilogram class are uniformly distributed, meaning that all weights within that class are equally likely to occur.Required:a. Find the probability that a package weighs between 15 and 16.5 kgs. (5) b. Find the probability that a package weighs less than 15 kgs. (5)c. Find the probability that a package weighs at least 18 kgs. (5)d. Calculate the variance and the standard deviation of the distribution. (5)e. Provide a sketch diagram to summarise the above information. Precisely show f(x), the mean value and the boundaries.
