A nutritiоn stоre in the mаll is selling аn herbаl supplement intended tо influence memory. To test the effectiveness (i.e., the influence on memory) of the herbal mixture, a skeptical researcher obtains a sample of n = 49 people and requests that each person take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes a standardized memory test (large numbers indicate better memory). The scores from the sample produced a mean of M = 33. In the general population, the standardized memory test is known to have a mean of µ = 30 and σ = 14. Do the sample data support the conclusion that the herbal supplement influenced memory? To answer this question, go through the 7 steps for hypothesis testing and use α = .05 (critical value = ±1.96).
