In the on-line resources you will find a file called sunspots. txt which contains the observed number of sunspots on the Sun for each month since January 1749. The file contains two columns of numbers, the first being the month and the second being the sunspot numbery, y(t). A. Write a program that reads in the data and makes a graph of sunspots as a function of time.
B. One way to demonstrate highly fluctuating data is to calculate moving average (or running average) for the data as you taking the average over small range of data rather than entire data. The moving average of the data, defined by
Yk = 1/2r sigma_m = -r^r yk + m
where r represents the range for taking average and the yk are the sunspot numbers. Calculate the moving average for r = 5, 10 and 100 and plot both the original data and the moving average on the same graph.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
