Suppose the size of a network flow is a normal random variable with parameters= 71GBytes and= 2.5GBytes. Use a Z-table to determine the following. (This requires mapping your normal distribution onto the standardnormal distribution.)

1. What percentage of the flows are greater than 72 GBytes?

2. Letmdenote the size of the flow. What is the value of "m"for which 88.30% of the flows are smaller than?
