Table 5 Probability of finding a tracer medicine in a sample outlet, by rural and urban location and manufacturing origin, 2006 and 2009 (40 medicines)
Location | 2006 | 2009 | ||
|---|---|---|---|---|
Manufactured in Tanzania and imported (20 medicines) | Imported only: not manufactured in Tanzania (20 medicines) | Manufactured in Tanzania and imported (21 medicines) | Imported only: not manufactured in Tanzania (19 medicines) | |
Rural | 0.53 (0.016) | 0.26 (0.014) | 0.49 (0.016) | 0.34 (0.016) |
Urban | 0.71 (0.015) | 0.56 (0.016) | 0.63 (0.016) | 0.58 (0.017) |
Difference | -0.18 (0.022) | -0.30 (0.022) | -0.14 (0.023) | -0.24 (0.023) |
Two sample test of proportions: | z-test = -7.91 | z-test = -13.27 | z-test = -5.93 | z-test = -9.91 |
H0 : Prural = Purban | Pr(|Z| < |z|) = 0.0000 | Pr(|Z| < |z|) = 0.0000 | Pr(|Z| < |z|) = 0.0000 | Pr(|Z| < |z|) = 0.0000 |
Ha : Prural ≠ Purban | Null-hypothesis is rejected | Null-hypothesis is rejected | Null-hypothesis is rejected | Null-hypothesis is rejected |
