The following sample data give the flexural strength (MPa) for concrete
beams of a certain type.
7.3, 6.3, 6.8, 7.0, 7.6, 6.8, 7.0, 6.3, 7.9, 9.0, 7.8, 9.7, 7.8,
11.6, 11.8, 10.7
Calculate a point estimate of the population coefficient of variation
and state which estimator you used.
0.214
O o/ji = 0.214
O s/ē = 0.221
O o/ī = 0.214
