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
