I only need help with the marked sections, thank you for the help I don’t know what went wrong

You wish to test the following claim (Ha) at a significance level of a = 0.01.
H,:P1 – p2 = 0
Ha: P1 - p2 # 0
You obtain 47.1% successes in a sample of size n1
Successes in a sample of size n2 =
639 from the first population. You obtain 56.7%
284 from the second population.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =| -2.71
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value:
=| 0.0067
The p-value is...
O less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O reject the null hypothesis
O accept the null hypothesis
O fail to reject the null hypothesis
