- Based on the following test data and batch ticket information,
(1) calculate the concrete density and yield
(2) determine whether it is under yielding or over yielding
(3) make a sand (s.g.=2.63) adjustment if under yielding
(this problem requires some critical thinking since it is a bit more complicated than the example in lecture note 13)
Test data:
Weight of the bucket with concrete: 44.72 lbs
Weight of the bucket: 7.98 lbs
Volume of the bucket: 0.249 cubic feet
Material batched:
Sand: 10,010 lbs
¾” Rock: 12,000 lbs
Cement: 3,530 lbs
Fly Ash: 600 lbs
Air: 5%
Water: 124 gallons
Quantity ordered: 7 cubic yards
(however, yield should be check with one cubic yard)
The mix was designed as 27.1 cubic feet per cubic yard.

1. Bone Density Test A bone mineral density test is used to
identify a bone disease. The result of a bone density test is
commonly measured as a z score, and the population of z scores is
normally distributed with a mean of 0 and a standard deviation of
1.
a. For a randomly selected subject, find the probability of a
bone density test score less than 1.54.
