**One-Tailed or Two-Tailed Test:** **State the Hypotheses:** - **df =** (Degrees of freedom for the test.) - **tα or t-value for the Critical Region =** (The t-value that marks the critical region for the hypothesis test.) - **sM =** (The standard error of the mean.) - **t =** (The calculated t-statistic.) **Decision:** (Conclude whether to reject or fail to reject the null hypothesis based on the t-statistic and critical region.)

**Memory Booster Effectiveness Study** A nutrition store in the mall is selling "Memory Booster," a concoction of herbs and minerals intended to improve memory performance. To test the effectiveness of this herbal mix, a researcher conducts a study with a sample of n = 16 people. Participants are asked to take the suggested dosage daily for four weeks. At the end of this period, each individual takes a standardized memory test. The research findings are as follows: - The sample produced a mean score (M) of 26. - The sample standard deviation (s) is 8, with a sum of squares (SS) of 960. In the general population, the standardized test is known to have a mean (μ) of 20. The question posed by the researcher is whether the sample data indicates that the "Memory Booster" has a significant effect. The test is conducted with a significance level (α) of 0.05.
