(a) Determine the mean and median of the given data.
(b) Determine the range, standard deviation, and coefficient of
variation of the given data.
(c) According to ACI 318 standard, the concrete samples are
adequately cured for testing if the average strength of the samples
is at least 85% of the target compressive strength. Does the given
result satisfy this requirement?
(d) According to ASTM C39 standard, the coefficient of variation of
a given compression test result for concrete testing must not
exceed 3.2% for it to be acceptable. Does the given result satisfy
this requirement?
