Question 1078065
2 sample proportion test
test statistic is a z. p1 hat is 0.276 and p2 hat is 0.349
if it is a two way test, which I would use, the critical value is -1.645.
z is -1.39
Fail to reject. p-value is 0.289; 0.0816 for a one way test

Note:
1. With a one way test (think in advance that there will be either no change or a change in one direction), the critical value is less, and one finds significance more often.  This should not be used to find significant tests but should be determined in advance.  It matters here because a one-way test would have a critical value of -1.282.
2. The formulae used are a two sample proportion test. (p1hat-p2hat)/sqrt ( p1(1-p1))/n1+p2(1-p2)/n2))
