a.Mean: _____________________Median: ____________________Mode: _____________________Range: _____________________Interquartile Range: __________
b. List the 5-number summary.
c. Variance: ____________________Standard Deviation: ____________
d. Calculate the lower and upper limits for determining if the data set contains any outliers. Lower Limit: __________________Upper Limit: __________________Do there appear to be any outliers? If so, which distances are outliers?
e. Construct a box-plot illustrating any outliers found in part (d). Be sure to label the axis appropriately.
f. Using the box-plot in part (e)would you describe the data distribution as symmetric, skewed left, or skewed right?

In West Texas, water is extremely important. The following data represent pH levels in ground water for a random sample of 102 West Texas wells. A pH less than 7 is acidic and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unusable or needs expensive treatment to make it usable.t These data are also available for download at...
