Consider the strength data for beams given in Example 1.2.
a. Construct a stem-and-leaf display of the data. What app ears to be a representative strength value? Do the observations appear to be highly concentrated about the representative value or rather spread out?
b. Does the display appear to be reasonably symmetric about a representative value, or would you describe its shape in some other way?
c. Do there appear to be any outlying strength values?
d. What proportion of strength observations in this sample exceed 10 MPa?
