You wish to test the following claim (HaHa) at a significance level of α=0.005. Ho:p1=p2 Ha:p1>p2 You obtain 249 successes in a sample of size n1=400n1=400 from the first population. You obtain 209 successes in a sample of size n2=362n2=362 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = ___________ What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = ________________

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic = ___________
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value = ________________
Given data
Sample size (n1) = 400
Successes of n1 (x1) = 249
Sample size (n2) = 362
Successes of n2 (x2) = 209
Then
p̂1 = x1 / n1
= 249 / 400
= 0.6225
p̂2 = x2 / n2
= 209 / 362
= 0.5773
