Ice cream sales (in gallons) fluctuate from month to month, depending on the season. A local ice cream lover would like to conduct a study to see if Blank Slate Creamery sells more ice cream than Ben & Jerry's, on average. Each month for the next 12 months, this ice cream enthusiast will record the total ice cream sales (in gallons) at Blank Slate Creamery and the total ice cream sales (in gallons) at Ben & Jerry's. Is this a paired data test or two independent samples test?
