The accompanying data is on cube compressive strength (MPa) of concrete specimens.
112.1 97.0 92.6 86.0 102.0 99.2 95.8 103.5 89.0 86.9
(a) Is it plausible that the compressive strength for this type of concrete is normally distributed?
A. The normal probability plot is acceptably linear, suggesting that a normal population distribution is not plausible.
B. The normal probability plot is not acceptably linear, suggesting that a normal population distribution is plausible.
C. The normal probability plot is not acceptably linear, suggesting that a normal population distribution is not plausible.
D. The normal probability plot is acceptably linear, suggesting that a normal population distribution is plausible.
