Here you are given the data of a graph . From this data tell:

what is the correct P value , the one tail or the two tail?

what is the 90% confindence interval?

Hypothesis Test for a Proportion

x1=number of successes group 1	689
n1=sample size group 1	7845
x2=number of successes group 1	513
n2=sample size group 1	7861.00
Sample Difference in Proportion (group 1-group 2)	0.02257
Standard Error (se)	0.0042
z test statistic	5.319
p-value (One-Tail)	0.0000
p-value (Two-Tail)	0.0000
