You are interested in how much time students spend on the internet each day. Here is data on the time spent on the internet (in minutes) for a particular day reported by a random sample of 20 students at a large college: 210 200 185 150 75 65 100 180 120 120 55 300 90 70 15 25 350 120 90 75 a) Find the 40th percentile b) Find the mean and sample standard deviation (do NOT use the formula, use the TI-84 instead), c) Determine outliers (if any). Justify your answer using the 1.5 QR rule. d) Would it be better to use the mean and standard deviation or the median and IQR to describe the center and spread of this distribution? Why
