Description: A researcher predicts that scores in treatment A will be higher than scores in treatment B. If the mean for the 10 participants in treatment A is 4 points higher than the mean for the 10 participants in treatment B and the data produced t = 2.095 Wh

From the provided information, The hypotheses can be constructed as: H0: µA ≤ µB H1: µA > µB Sample size (n) = 10 The test statistic value is 2.095.Assuming level of significance (α) = 0.05 The degree of freedom = n – 1 = 10 – 1 = 9 The critical value of t at 9 degree of freedom with 0.05 level of significance from the t value table is 1.833 (one tailed) and ±2.262 (two tailed). Since, the test statistic is greater than critical value (one tailed), therefore, the null hypothesis would reject. And the test statistic is less than critical value (two tailed), therefore, the null hypothesis would fail to reject. Thus, the correct option is c). With an alpha = .05 reject the null for one tail but fail to reject with two tails
