In a concrete production plant, the average concrete production of is projected as uo=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, Montly concrete production samples (tons/month) 5 6 | 7 10 1 2 2340 3616 3 4 8 9 11 12 5250 6800 | 7950 | 4910 | 9025 | 7910 | 5820 || 4100 | 3000 1808
