b. The best graphical method for portraying these data is the Pareto Chart which arranges the data in descending order and then does the plotting in the form of bars and also contains a line representing the cumulative percentage of defects.

c. On the analysis of data, I have reached the below conclusions:
i. Majority of the students spend their time in Sleeping (i.e. 37%)

ii. Beyond Sleeping, students spend their time in Leisure and sports or Educational activities. The majority of this 31% of students spend time in Leisure and Sports (i.e. 17%) and not with the much difference spends time in Educational activities (i.e. 14%)
.
iii. The least of the students spend time in grooming.

iv. Here we have an average of 13%. So activities done by students nearly average are Leisure, educational activities, Working and related, and others.

v. Here we can treat sleeping and grooming as an outlier as it is far from the average.
