**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.

You want to determine if diet impacts body weight. You recruit 60 subjects, assigning 20 each to either one of two dietary interventions or to maintain their normal diet. You measure body weight before and after the intervention and calculate the change in body weight (post minus pre weights). To determine the diet effect on the calculated change in body weight, you would use a .Assume all assumptions are met for a parametric test.

The corrosive effects of various soils on coated and uncoated steel pipe was tested by using a dependent sampling plan. The data collected are summarized below, where d is the amount of corrosion on the coated portion subtracted from the amount of corrosion on the uncoated portion. Does this random sample provide sufficient reason to conclude that the coating is beneficial? Use a = 0.01 and assume normality. n- 40, Σd- 207, Σα? = 6199 (a) Find t. (Give your answer correct to two decimal places.) (ii) Find the p-value. (Give your answer correct to four decimal places.) (b) State the appropriate conclusion. O Reject the null hypothesis, there is significant evidence that the coating is beneficial. Reject the null hypothesis, there is not significant evidence that the coating is beneficial. Fail to reject the null hypothesis, there is significant evidence that the coating is beneficial. Fail to reject the null hypothesis, there is not significant evidence that the coating is beneficial.
