SITUATION 1 Consider the following results of compression test for twelve 28-day concrete cylinder samples from a particular mix batch during construction. (Note: The data are expressed in psi. The minimum required 28-day compressive strength of concrete for the particular construction project is 4000 psi). 4031 4112 4063 3965 3994 4002 3895 4218 3780 3954 4015 3940 (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?
