1) A group of researchers want to look at whether left handed subjects do better on free recall tests from a visual environment. 30 left handers were placed in a very plain room with a shelf of random objects on one wall. Afterwards, they were prompted to recall as many things as they could remember on the shelves (keep in mind they were not told beforehand to encode the items). Out of 35 items, the average person will score about a 26. Of the sample, the researchers found that the subjects scored 28.5 items, with a standard deviation of 3. (α= .01)
