Concrete Production Plant
In a concrete production plant, the average concrete production of
is projected as µo=5500 tons/month according to the production
plan. In order to verify these data, the 12-monthly concrete
production samples are randomly observed as in the following
table. CALCULATE ZCAL and Zcr by using sample standart
deviation S as an estimate population standart deviation o. Is
there any difference between the average projected-concrete
production and the average observed-concrete production
with the level of significance (a)? a = 0. 05,
