Calculate the value of the test statistic Round intermediate
Calculate the value of the test statistic. (Round intermediate calculations to 4 decimal places and final answer to 2 decimal places.)
Calculate the p-value. (Round your answer to 4 decimal places.)
| Consider the following competing hypotheses and accompanying sample data. Use Table 1. |
| H0: p1 p2 = 0.20 |
| HA: p1 p2 0.20 |
Solution
p1 = 0.687
p2 = 0.301
p1-p2 = 0.386
p1-p2-0.20 = 0.186
z score = 12.9336
p value =0
Yes, since the value of the test statistic is more than the critical value of 1.65
