You are interested in how much time students spend on the internet each day. Here are data on the time spent on the internet (in minutes) for a particular day reported by a random sample of 30 students at a large college:
a) Make a histogram of these data. Is the shape symmetric or skewed?
b) Find the 5 number summary and P65.
c) Find the mean and sample standard deviation.
d) Are there any outliers? Justify your answer.
e) Would it be better to use the mean and standard deviation or the median and IQR to describe the centre and spread of this distribution? why?
