The makers of the Liquid Braino® brand energy drink claim that their product contains special ingredients that can improve a person’s memory. To test this claim, a public interest organization randomly selected 12 individuals, and then randomly assigned each of these individuals to one of two possible groups:i. The experimental group (“Braino Group”), in which each subject drank a case of Liquid Braino.ii. The control group (“Placebo Group”), in which each subject drank a case of a soda that looked and tasted exactly like Liquid Braino, but did not contain any of Liquid Braino’s special ingredients.(No subjects knew which type of drink they had been given.) Later, all subjects were given a memory test, in which higher scores indicate better memory. The scores earned by the subjects in each group are listed below:.9px;=”” 12px=””>Braino GroupPlacebo Group908765667076807630325544(Assume that the underlying populations are normally distributed, with equal variances.)
