A boss wants to show that productivity decreases when the boss leaves the office. An office of 26 employees handed in productivity reports when the boss was absent (M1=5, SS1=250) compared to 36 employees who handed in reports when the boss was present (M2=8, SS2=420). a) What is the null and alternative hypothesis? a Ho:μ 1-μ2≠0; H1:μ 1-μ2=0 b Ho:μ 1-μ2<0; H1:μ 1-μ2>0 c Ho:μ 1-μ2=0; H1:μ 1-μ2≠0 d Ho:μ 1-μ2>0; H1:μ 1-μ2<0 b) Compute tobt? c) Compute df?

Ho:μ 1-μ2<0; H1:μ 1-μ2>0 |
|
c |
Ho:μ 1-μ2=0; H1:μ 1-μ2≠0
|
|
d |
Ho:μ 1-μ2>0; H1:μ 1-μ2<0
|
b) Compute tobt?
