1. Decide whether you reject or fail to reject the null and interpret for the following statistical tests (4 points) a. Ho: Hw = 80; Ha: Hw 80; a = .05; Zev = +1.96; Zobtained = +2.33 b. Ho: Hw = 80; Ha: Hw 80; a = .05; try = 12.042; tobtained = +2.23 C. Ho: Hw = 80; Ha: Ww & 80; a = .05; tv = -1.697; tobtained = -1.58 d. Ho: H1=H2; Ha: M1 & H2; a = .05; try = -1.64; tobtained = -1.58
