I need help finding the p-value

Consider the hypothesis test below.
Ho: p 1 - p 2 < o
На: р 1 -р2> 0
The following results are for independent samples taken from the two populations.
Sample 1
Sample 2
ni = 100
n 2 = 300
p1 = 0.27
p 2 = 0.13
Use pooled estimator of p.
a. What is the value of the test statistic (to 2 decimals)?
3.27 O
b. What is the p-value (to 4 decimals)? Use z-table.
0.0116
c. With a =
.05, what is your hypothesis testing conclusion?
Conclude the difference between the proportions is greater than 0
