does this data meet the assumptions for a two population proportion hypothesis
using PHANTOMS
Hypothesis test results:
Difference | Count1 | Total1 | Count2 | Total2 | Sample Diff. | Std. Err. | Z-Stat | P-value |
---|---|---|---|---|---|---|---|---|
p1 - p2 | 9 | 31 | 8 | 30 | 0.023655914 | 0.1148271 | 0.20601333 | 0.8368 |
Hypothesis test results:
Difference | Count1 | Total1 | Count2 | Total2 | Sample Diff. | Std. Err. | Z-Stat | P-value |
---|---|---|---|---|---|---|---|---|
p1 - p2 | 9 | 31 | 8 | 30 | 0.023655914 | 0.1148271 | 0.20601333 | 0.8368 |
From the given data n1 = 31 , x1 = 9
n2 = 30 , x2 = 8
sample proportion (1) = 9/31 = 0.29
sample proportion (2) = 8/30= 0.27
since n11 = 9 > 5
n1*(1-1) = 22.01 > 5
since n22 = 8 > 5
n2*(1-2) = 21.9 > 5
so conditions are satisfied
