Consider two samples from two normal populations: 24 25 24 25 23 2? 23 23 2? 25 and 21 1? 21 22 14 14 21 26 21 26 23 21 Suppose we wish to test H0 p1 - p2 = 4 against Ha p1 - p2 =- 4. Select the following correct choices: a) not reject Ho at a = 0.05. Ob) reject Ho at a = 0.02. O c reject Ho at & = 0.05. (d) not reject Ho at a = 0.02. Oe) reject Ho at ox = 0.03. Of) not reject Ho at a = 0.03. Hide hint for Question 6 t.03=2.150, t.02=2.398, df=9
