Suppose that an average weight loss of 1 pound (71) and standard deviation of s = 7 pounds were found in each of the following scenarios. Further, assume weight loss is normally distributed. For each case, compute the test statistic, find the approximate p- value and make a conclusion about the null hypothesis. Round t-statistics to two decimals. i. Scenario 1: a sample of size n = 10 A. t- and dfa B. The p-value corresponding to the correct test statistic is 0.331. This p-value suggests against the null hypothesis, (Choose One) Little to no evidence Borderline/ Weak evidence Moderate evidence Substantial/Strong evidence Extremely strong/Overwhelming evidence ii. Scenario 2: a sample of size n = 120 A. t = B. The p-value corresponding gests Little to no evidence and dfa to the correct test statistic is 0.0601. This p-value sug- against the null hypothesis. (Choose One) Borderline/ Weak evidence Moderate evidence Substantial/Strong evidence- Extremely strong/Overwhelmin evidence iii. Scenario 3: a sample of size n = 1050 A. t = and df B. The p-value corresponding to the correct test statistic is 0.000002. This p-value against the null hypothesis. (Choose One) suggests Little to no evidence Borderline/ Weak evidence . Moderate evidence Substantial/Strong evidence Extremely strong/Overwhelming evidence
