Question

Energy Surplus makes low-cost energy drinks, and they wanted to monitor their caffeine content (mg) per bottle. They observed three separate bottles from 5 different batches to see if they were hitting their target of 35 mg per bottle. Based on the information given below, what is the X Double Bar for the data set? (Round answers to, two decimals) Bottle 1 34.96 34.17 34.93 34.17 34.28 Bottle 2 35.22 33.64 33.87 33.74 35.37 Bottle 3 35.51 32.74 34.49 36.60 36.54 Batch 2 3 4 34.68 35.82 36.11 34.24

Explanation / Answer

Mean of bottle 1=(34.96+34.17+34.93+34.17+34.28)/5=34.502
Mean of bottle 2=(35.22+33.64+33.87+33.74+35.37)/5=34.368
Mean of bottle 3=(35.51+32.74+34.49+36.60+36.54)/5=35.176

X double bar=(34.502+34.368+35.176)/3=34.682
