You are writing code to copy software over the network. Given a file size and a constant packet/buffer size, you can easily calculate the number of successful packet deliveries required to copy the file.
What you cannot know beforehand is the time it takes to copy these packets. But users love to see a progress bar which estimates a duration left for copying the file.
a) Suppose you have a file that needs 10 same-size packets to be delivered and the first 9 packets have taken 123, 142, 130, 125, 132, 150, 140, 133, and 148 miliseconds respectively. Estimate the time it takes to deliver the last packet.
b) Now suppose you have a file that needs 1.000 same-size packers to be delivered and you have just delivered the first 499 packets. The average time for the 499 packets is 148 miliseconds, and the last 5 packets have taken 124,140, 132, 134, and 140 miliseconds respectively. Estimate the time it takes to deliver all packets.
