Answer:
Since p > alpha, we accept H0, there is no evidence to prove that p1 is greater than p2
Step-by-step explanation:
Set up hypotheses as
(Right tailed t test)
Alpha = 0.05
Sample I II Total
X 117 141 248
N 249 312 561
p 0.4700 0.4519 0.4420
p difference = 0.0181
Std dev =
=0.0427
z statistic = 0.424
p value = 0.33724
Since p > alpha, we accept H0, there is no evidence to prove that p1 is greater than p2
